You can push F11 key repeatably while starting your machine.This will bring you in to recovery mode.Just follow the prompts and you will wind up with factory default settings.If this won't work you can get a free recovery disk from HP.You will need to change the boot order from :A to CD DVD first devise checked so that it will start off of the setup CD.The order should look like this CD/DVD #1,C:drive #2 .Internet boot # 3.A: # 4.(Floppy drive).When you first start up the boot menu will be displayed so try and tap that key to access the menu.You may have to use your keys to navigate,arrow keys space bar,+ - and enter keys.Just hi light your choice and hit y or n. Take your time and just look around .or just scroll over to boot order hi lite A: press - until it goes to the botteom tap tap tap .CD/DVD drive should now be first.Exit saving changes.Before you shut down insert recovery CD, Then shut down and power back on and when asked if you want to do a quick format choose yes.One of HP's techs may walk you threw this if your going through this the first time.Here's a link for your free recovery CD. I have read that HP will no longer be making PC's in the future.They will be doing software instead.Printers should be OK..http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00810334&cc=us&dlc=en&lc=en&product=3807258
Thank You for choosing FixYa Feel free to return if you have any questions.

Well here is a quick solution for you. I love reading some of the most crazy responses on this site, but I did want to give you a possible solution. I am Guru... I used to modem pool three 56k modems before broadband was available... (most people won't even know what I just said, but the other gurus out there can appreciate it)....

Moving right along...
I got that same error this morning, and fixed it in less than 1 minute.

Like I said, I am not your average techie- I have full OEM CD or DVD versions of Win95a, b,c - up to Win 7Home Prem (another one the gurus could love, most people did not know Win95 had three versions... lol.. there was no such thing as live updates back then)

1. Get an OEM/Retail Full version of WinXP, Win7HP, etc (what ever it is you have installed)
2. These disks can boot your computer and restore it.. I DO NOT recommend HP Restore Disk Wizard because they will burn fine, but when you try to use them, you will get read errors and have to PURCHASE restore disks from HP (disagree? Google for yourself ).


Proof of concept ! (Got to love it)
See below, I put my Full version Win7HP disk in, restarted the computer.
2. Wizard starts like you are doing a full install but, you will have an option to repair existing Win7HP
3. Let the Wizard find your current install
4. The wizard will also attempt to find the problem, and give advice on how to repair.
5. In this case you can see the results it gave me.
6. So I clicked OK to repair and restart...
7. Now I am writing this response....

Thanks for reading...

That is the "Windows boot manager missing" error. The above have listed the solution. To save your files on the hard drive removed it and dongle it off another pc as a slave drive and drag and drop your files. The operating system will need to be reloaded fresh.

Try this. Restart your computer and press F8 repeatedly and enter "Safe mode". After going into safe mode disable driver signing. Then restart the computer.
You have not provided the info which Windows you are using like XP, Vista or 7?
The driver disable is done differently depending n the version of the Windows.

All you have to do is to get the recovery disc from any computer store or take it to the repair centre. good luck..

Incase if you dont have your recovery CD, and u cant buy another one. then the only option is to put the same operating system CD and during installation select the repair installation that will work.

Although I agree with Justin on most of his points, there are a couple of things I would like to bring up.
1) The error code points to the boot manager, which may indicate a corrupt sector on the hard drive, which is a far cry from being completely failed.
2) You didn't mention the make or model of the laptop, but if you are already licensed for Windows you may not have to purchase the software again. Contact me with your model specifics and I will try to help you.
3) Not a big fan of Best Buy, but they will most likely have the correct part. Newegg.com is another very good option. Since there are several types of hard drives, including SSD, SATA, and ATA/6, you need to know what type of drive you currently have. Also you may be able to replace a failed SATA with an SSD, which will give you faster startup times, more reliability (longer lifespan) and improved performance. They cost a bit more but the prices are coming down to fairly reasonable.
4) If this PC is less than a year old, it's probably still under warranty. Also they should provide you with the O/S disc in this case also. (under a warranty hard drive, I have heard of a new drive being sent out with instructions on how to install it)
5) Even if the drive won't boot, it's likely (very likely) that data (documents, music, photos, etc.) can still be recovered. Contact me if you would like help with this part.

Welcome to Fixya

This is a common problem especially if one of the windows system files is missing or corrupted. At this point, there is nothing that you can do but to get hold of the restore disk to reinstall windows in your computer.

Thank you for using Fixya!

Most probable is that the hard drive itself is bad. This error typically occurs when the windows boot loader / partition can't be found. The "device is inaccessible" is a big red flag to me. This means it can't read info off the hard drive. You will need to

• Replace the hard drive
• Purchase a recovery disc set from HP

For the drive you can buy them from Best Buy or any other big box electronics retailer or online at places such as www.newegg.com or www.tigerdirect.comJust make sure your buy a 2.5" SATA drive whatever size you want. You can pick up a 500GB drive from Best Buy for about $45
The recovery discs typically run $15 - $60. HP's are usually like $20.Here is HP's "how to order recovery media"http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00810334

Scroll down to the sectionOrdering recovery discs from HP in the United States and Canada

You will need your model and serial # on the back to order the correct media. Once you have installed the hard drive and media
