unsuccessful installation

Everytme I install Vista, it restarts and askes to rollback or go back to the previous version. I press rollback, and when it goes to the logon screen, it says unsucessful installation and restarts again but to the previous version. What do I do to make Vista work?

You can start by telling us your system specs. How did you launch setup, did you launch in an existing installation Windows, did you boot from the DVD, use Virtual Drive software such as Daemon Tools, NERO Image Drive? Have you checked the integrity of the ISO Image you downloaded, it could also be a bad burn.
I use the one from Ahead Nero http://ww2.nero.com/nero6/eng/Nero_MD5_Verifier.html
Here are the MD5/CRC values for x86 or x64 depending on which every ISO you downloaded:
x86 - File Size = 3.12 GB (3,355,598,848 bytes) - CRC Value = 0x67E089E0 - MD5 Value = 0E733AB1A8E8FF9A8684FD3639332773 x64 - File Size = 4.01 GB (4,309,368,832 bytes) - CRC Value = 0x48697711 - MD5 Value = E43502D0A15EADD551119D5639859E04
Paste the MD5 Checksum for either x64 or x86 depending on which one you want check in Step 1, Step 2 - Browse to where you stored the ISO on your drive and open it and it will automatically start the varification process and generate the has in the third field, if it matches Step 1, then you are safe.
