Installation of Windows 7 freezes on Dell Dimension 5150

It is an original MS W7 Home Edition DVD allowing 3 upgrades from Vista or XP. I used it already succesfully in 2 cases (from XP to 7) and now I need to use it (for the 3rd and last) time.
I do not get any chance for any of the advices about Clean Install. Booting frm the DVD I get the black screen with "hit any key..." than files are loaded, then expanded, than the black screen with "Windows is starting" then the crash.
I am left with this annoying boot manager asking for "use previous installation" or "continue with the setup".
I need to get rid of it and return to a stable XP-status (thus w/o this boot manager) first.
But I will try the 2GB suggestion first.

Hi
I just made it following Ztruker's suggestion. It was even written on the bios setup menu that some os installations may fail if more than 2GB RAM installed...
Would like to thank you all for your time and the good suggestions!
The thread is now closed.

Ztruker's suggestion worked smoothly: Remove all but 2GB RAM and try again. The installation succedded w/o any problem.

Thank you all guys for the time and suggestions!

Minas2, how goes the install. I have been having almost the exact same problem, and I am very curious if you got the issue resolved.

In my case, I was able to reboot in debug mode and could see that the system was locking up when the operating system was loading DISK.SYS. Do don't know if there is a driver issue with the CD/DVD, or if it's with the Mirrord (Raid 1) hard drive.

Win7 doesn't much like RAID as all we see are complaints and no positive comments on RAID here.

If working through these steps for Troubleshooting Windows 7 Failure to Boot
can't get it started then I'd consider unRAIDing it from the controller which pops up at boot, and in the SATA controller settings in BIOS setup, remove one HD to clean reinstall to target HD, afterwards plug back in other HD to use for storage for files and Win7 backup image.

As already written: ... Ztruker's suggestion worked smoothly: Remove all but 2GB RAM and try again. The installation succeded w/o any problem. ... It was even written on the bios setup menu that some os installations may fail if more than 2GB RAM installed...
After the installation complete successfully you can again add the additional RAM.
