CD drive not seeing sys disk to boot

1. Use the Windows XP startup disks or the Windows XP CD to restart your computer.
2. When the "Welcome to Setup" screen appears, press R to select the To repair a Windows XP installation using Recovery Console, press R option.
3. Type the number of the Windows installation that you want to access from the Recovery Console, and then press ENTER.
4. Type the administrator password when you are prompted, and then press ENTER. If no administrator password exists, just press ENTER.
5. At the command prompt, type the following commands (press ENTER after each command): cd \windows\system32\drivers
   
   ren ntfs.sys ntfs.oldNote This step renames the corrupted Ntfs.sys file to Ntfs.old. If the Ntfs.sys file is not found, the file is missing.
6. At the command prompt, type the following command, and then press ENTER: copy cd:\i386\ntfs.sys drive:\windows\system32\driversWhere cd is the drive letter for the CD-ROM drive that contains the Windows XP CD, and drive is the drive where you installed Windows XP.
7. Remove the Windows XP CD from your CD-ROM drive, type quit at a command prompt, and then press ENTER to quit the Recovery Console.
8. Restart the computer

If it happens that you are prompted by the following error message "DISK BOOT FAILURE INSERT SYSTEM DISK AND PRESS ENTER", "No system disk", it means that the computer did not find the operating system to start (boot).

Causes:


A diskette or CD has remained in the drive

Check out if any diskettes, CD-ROM or DVD-ROM are present in respective drives, remove them and restart your computer

The boot sequence is incorrect BIOS



Enter the BIOS setup of your computer and edit the boot (boot sequence) so that the computer starts primarily on drive C:
A new hard drive was installed

In the case that a new hard drive has been installed, this message is quite normal.
Just insert the correct CD to install the system (usually Windows), then restart, while making sure the CD-ROM is first in the defined in the BIOS setup as first boot sequence.
The hard drive is unplugged

Open the system unit and check that power cable of the hard drive is properly connected.
Corrupted system files

It may happens that some system files needed to boot the computer have been deleted /damaged or that the boot sector of the disc is damaged.

To determine this, start the computer with a system disk or CD-ROM installation of Windows (via the Recovery Console), and once started, type Dir C: to check if the contents of drive C: are accessible. If its ok then the problem comes from missing or damaged files, then you just have to run the command:

fdisk /mbr
sys c:



Note that before any restoration of the boot sector with the command fdisk / mbr, (supposing that there is a virus), it is recommended to use an antivirus running under DOS, such as
f-prot.

Damaged disk

If the hard disk or a partition is damaged:
If it detected in the BIOS setup, there is a chance that it is
not out of service.
If it is, try reinstalling the system through the installation CD, in order to reformat or recover the partition using a utility.

To resolve this problem, replace the missing or corrupted Ntfs.sys file:

1. Use the Windows Vista startup disks or the Windows Vista CD to restart your computer.
2. When the "Welcome to Setup" screen appears, press R to select the To repair a Windows Vista installation using Recovery Console, press R option.
3. Type the number of the Windows installation that you want to access from the Recovery Console, and then press ENTER.
4. Type the administrator password when you are prompted, and then press ENTER. If no administrator password exists, just press ENTER.
5. At the command prompt, type the following commands (press ENTER after each command): cd \windows\system32\drivers
   
   ren ntfs.sys ntfs.oldNote This step renames the corrupted Ntfs.sys file to Ntfs.old. If the Ntfs.sys file is not found, the file is missing.
6. At the command prompt, type the following command, and then press ENTER: copy cd:\i386\ntfs.sys drive:\windows\system32\driversWhere cd is the drive letter for the CD-ROM drive that contains the Windows Vista CD, and drive is the drive where you installed Windows Vista .
7. Remove the Windows Vista CD from your CD-ROM drive, type quit at a command prompt, and then press ENTER to quit the Recovery Console.
8. Restart the computer.
9. rate me 4 thumbs up please

you can click on computer then right click on the drive that you want to format the you will see the option FORMAT,or you can use a recovery disc and do a clean install,how to do a clean install? put the disc on the dvd drive nad then turn off the pc,turn it back on then keep on tapping f12,select boot from cd/dvd or boot from odd

You would need the full version copy of Microsoft Windows XP or Win 7 with the CD key to reinstall the OS after you format the hard drive.

Hi:
Some older laptops don't always recognize the full size hard drives bigger than 134 Gb, but they usually show up in your bios. There isn't an easy way to install it wrong, so if the drive wasn't new to you, it might have a problem...New Hard drives come with installation CD's, but that won't do you any good until the drive is recognized

When it's booting, try to access the setup, aka BIOS. See if you can set CD/DVD as a booting option. As the top BOOT device. Then see if you can boot your installation CD. You may be able to format your drive during the installation - if the hard drive hasn't failed?

If you just installed windows then take the cd out and let the computer reboot on its own. Windows will ask you to replace the OS disk later.

So just restart the computer with nothing in the CD drive.

Also make sure in BIOS that the Hard drive is the first boot device. Don't need the CD drive as first anymore.

See if that helps.

Your ACER Extensa should have come with a recovery CD. Just boot up to that CD and follow the instructions.
