How To Make Vista Bootable DVD with WIM Downloaded Files If you have purchased Windows Vista online and taken the delivery of the latest operating system via web download from Windows Marketplace, you would ends up with a few downloads with .wim and .exe file extensions. Rather than paying additional shipping and handling charges, you can burn or create a bootable ISO DVD image from downloaded Vista files with the following trick, where the .iso image can subsequently write to a DVD. The DVD created will be the typical 32-bit Windows Vista DVD that available in retail channel, and can be used to clean install.

How to make a bootable Windows Vista ISO DVD media

1. Put all 3 downloaded files (namely install.wim, boot.wim and an executable X13-49120.exe) in the same folder (for this tutorial, let’s assume the files are put on C:\ else you need to modify the path accordingly).
2. Run the X13-49120.exe executable. Windows Vista Setup Preparation will create a new folder “Vista” inside the folder and will populate the folder with all necessary Vista setup files which takes up about 2.52 GB disk space.
3. Exit from the Install Windows screen.
4. Download CDimage 2.52
5. Extract CDimage from CDimage.zip to the C:\ root directory.
6. Open a command prompt shell, and run the following command:

cdimage.exe -lVISTA_EN_DVD -m -u2 -bC:\Vista\boot\etfsboot.com C:\Vista\ C:\Vistax86.iso

Bootable Windows Vista x86 DVD ISO image in UDF format will be created as vistax86.iso in C:\ or any folder you specified above.
7. Burn the newly create ISO with a CD/DVD burning software such as Nero or Alcohol 120%. Try to burn at low speed (i.e. 4X) and turn on verification to ensure that the DVD creation is fine.

Create a Windows Vista ISO image and DVD with Oscdimg

Another possible way to create a bootable Vista ISO and DVD is by using Oscdimg CD-ROM and DVD-ROM Premastering Utility, available via WinPE (Windows Preinstallation Environment) via Business Desktop Deployment 2007 or Windows Automated Installation Kit (AIK)

1. Complete step 1 - 3 as above.
2. In the command prompt window, run the following command:

oscdimg -bC:\Vista\boot\etfsboot.com -h -u2 -m -lVISTA_EN_DVD C:\Vista\ C:\VistaDVD.iso

A VistaDVD.iso UDF DVD image will be created and can be used to boot the computer from DVD to install Vista.
3. Burn the ISO image file by using last step above.

SOURCE: Bad image checksum and not reading a hard drive

Hello,

The checksum is a long number that is computed. This sounds like maybe your cpu is bad or going bad. You don't provide enough information to determine a solution. So...

If you are trying to install Windows and you get this error, your memory may be bad (google for memtest86), your CPU may be bad, or your CD/DVD drive may be bad. Try the easiest first. Test your memory and change your CD/DVD drive.

If Windows is already installed, your memory or CPU is bad. Test your memory. If it's good, I would have to assume the CPU is bad.

Hope that helps.

SOURCE: acer aspire 2920z cannot boot hard disk drive

Well either way it's probably not a good thing. You've either lost critical files or damaged the boot sector of the drive. The question is do you have valuable files on that hard drive that you need? If the drive is going bad, the more you run it the less chance you have of retrieving those valuable files. If you know how you can put in the XP CD and boot off it and do some repair but DO NOT try to re-install Windows at this time as it may try to format your drive and then your valuable files will be gone. You should have some professional help to try to repair your current windows. The best way to solve this is to probably get another hard drive as they are pretty cheap. Exchange drives and re-install windows then get someone knowledgeable to retrieve your valuable files from the old hard drive then send it back to the manufacturer and see if you can get a new one on warranty and keep it for a spare or sell it.

Acer computer ask for bootable any help?


If your computer is asking for a bootable disk drive on startup, it typically indicates drive failure and your harddrive needs replacement. Sorry for the badnews.

Aspire 5742 turns on and off contiously


After you remove the hard disk, did you try to boot the machine with a bootable flash drive or CD/DVD? Booting from a Live Linux disc you create on a different machine (free for download and use) or something like that will determine if the rest of the machine has any issues or not. If it will boot like that, then you may have a faulty hard disk, and need to replace it. I hope you have been backing up your data if this is the case.

When i turn on my Acer Aspire One D255 it says: "check cable connection! PXE-M0F: Exiting Intel PXE ROM. No bootable device -- insert boot disk and press any key"


The PXE ROM is part of your system's network interface controller. It is being entered on your system's startup to look for a bootable image on a physical network connection and if found, to boot from that image. If there is no network cable connection to your system or if there is but no bootable device is found on that connection, the result is the error message that you got. As to why your system is entering the PXE ROM can be explained by looking at your system's Setup Utility,,,

Press F2 while powering up to enter the Setup Utility and use the cursor control keys to go to the Boot tab which then shows the Boot priority order. The default order is as follows...
1. IDE0
2. IDE1
3. USB FDD
4. USB HDD
5. Network Boot : LEGACY PCI DEVICE
6. USB CDROM
Your system's internal hard disk drive should be listed beside IDE0 and it will be accessed first to look for a boot record. If the drive fails to boot, the next devices in the list will be accessed accordingly until either a bootable device is found or the last item which is USB CDROM. If a USB CDROM is plugged in on one of the system's USB ports, it will be checked for a bootable record and if not found or no CDROM is plugged in, then the system displays the last part of the message -- insert boot disk and press any key.

Press F12 while powering up enters the Boot Menu which has the Boot Option Menu. This menu should show by default the following...
1. IDE 0: (the name/type information for your system's internal hard disk drive
2. Network Boot: LEGACY PCI DEVICE

If there is no hard disk drive information shown beside IDE 0, then the possibilities are that
1. there is no internal hard drive present
2. there is a hard drive but it has failed
If there is hard disk drive information and pressing enter to select it does not result in an operating system startup, then the drive's startup partition has been wiped and so it has no bootable image.

If there seems to be an internal hard drive present but it has no bootable image, you may attempt recovery from the installation images in the hidden partition. The recovery allows restoration of...
1. operating system to factory defaults
2. applications (selectable)
3. drivers (selectable)

Press Alt and F10 keys together while powering up and the Acer logo is showing to enter Acer's eRecovery Management. Follow the instructions to do the recovery.

Upon startup before anything else happens (except asking me if I want to press f2 for setup) my aspire one netbook says: For Atheros PCIE Ethernet Controller... v1.0.0.5(1/22/09) check cable...


This means you should install an Operating System.
If your notebook doesn't have a dvd drive you can install the Operating System with an external drive (dvd, USB flash drive or hard drive). and press F12 when it starts to select the booting device.

I have an Acer Aspire 5720, ive had it for a year now and it is starting to slow down. I have lost the booklet to it and i need to do a master reset on it. Ive already backed everything up im just finding...


This was taken straight out of the manual for your model, which can be found here.

Acer eRecovery Management
Acer eRecovery Management is a tool to quickly backup and restore the system.
You can create and save a backup of the current system configuration to hard
disk, CD or DVD. You can also backup/restore the factory default image, and
reinstall applications and drivers.

Acer eRecovery Management consists of the following functions:

1 Create backup
2 Burn backup disc
3 Restore and recovery

This chapter will guide you through each process.
Note: This feature is only available on certain models. For systems
that do not have a built-in optical disc burner, plug in an external
optical disc burner before entering Acer eRecovery Management
for optical disc-related tasks.

When using Acer eRecovery Management, you may be prompted to enter the
Empowering Technology password to proceed. The Empowering Technology
password is set using the Empowering Technology toolbar or when first running
Acer eLock Management or Acer eRecovery Management.

Create backup

You can easily create full and fast (incremental) backup images of your system
configuration to hard disk from the main Acer eRecovery Management screen.
Note: Fast (incremental) Backup is only available after a Full
Backup is made.

1 Press <Alt> + <F10> or select Acer eRecovery Management from the
Empowering Technology toolbar to start Acer eRecovery Management.
2 In the Acer eRecovery Management window, select the type of backup you
want to create using Full or Fast.
3 Follow the instructions on screen to complete the process.

English
Burn backup disc
Using the Burn Disc page of Acer eRecovery Management, you can burn the
factory default image, a user backup image, the current system configuration,
or an application backup image to CD or DVD.
1 Press <Alt> + <F10> or select Acer eRecovery Management from the
Empowering Technology toolbar to start Acer eRecovery Management.
2 Switch to the Burn Disc page by selecting the Burn Disc button.
3 Select the type of backup (factory default, user, current system,
application) you would like to burn to disc. Choosing to burn a user backup
will burn your most recently created backup image to disc.
4 Follow the instructions on screen to complete the process.
Note: Create a factory default image when you want to burn a
bootable disc that contains your computer's entire operating
system as it was delivered to you from the factory. If you wish to
have a disc that will allow you to browse the contents and install
selected drivers and applications, create an application backup
image instead — this disc will not be bootable.

Restore and recovery

The restore and recovery features allow you to restore or recover the system
from a factory default image, from a user created image, or from previously
created CD and DVD backups. You can also reinstall applications and drivers for
your Acer system.
1 Press <Alt> + <F10> or select Acer eRecovery Management from the
Empowering Technology toolbar to start Acer eRecovery Management.
2 Switch to the restore and recovery page by selecting the Restore button.
3 Select the backup point you would like to restore from. You can also
choose to recover the system from a factory default image, recover from a
previously created CD/DVD or reinstall applications and drivers.
4 Follow the instructions on screen to complete the process.

3 bleeps when i boot up acer aspire 9300


This means that your graphics chip is pootched. Since the graphics card is usually fixed to the motherboard the only way to repair is to take it in for service. Since the service may be ½ the cost of a new laptop it may be best to just purchase a new one.

Hello


The Bios should not be your problem and the MBR doesn't have anything to do if you didn't play with Windows installations or with any utility to create an image of your hard drive.

 

To understand where the problem is coming from:

- Ask someone to go to http://www.knoppix.org/ and download a Knoppix CD

- Create a bootable CD from the ISO downloaded

- Enter in your Laptop BIOS settings and change the first bootable device as the CD/DVD

- Insert the Knoppix CD and boot your Laptop

- Knoppix will start and ask boot:

- Just hit Enter

- When Knoppix has finished and it's running you will have a nice graphic interface

- click on the HD icon on the desktop and see if you can see your files, if not you have a bad Hard disk

- Knoppix has also a utility to test the memory too.

 

If you tryied to install another copy of Windows or you made an image using some software like Ghost, you have to:

- boot from a floppy disk (Download and create from here http://www.bootdisk.com/bootdisk.htm, I suggest Windows 98 SE)

- At the prompt type FDISK /MBR and press Enter

ATTENTION: If you type something different you may distroy all your files on your hard drive
