How To Make Vista Bootable DVD with WIM Downloaded Files
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.

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.

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.

if your pc starts ok with no cd in than do it like that if you see this error all the time it means your hard drive is shot, or erased, or partially erased and needs to be setup again or replaced. got nothing to do with acronis if it does this all the time even with no cd in drive.
