Windows 7: Frozen at Expanding Files

10 May 2009   #1

Vista Home Premium
Frozen at Expanding Files

I have recently decided to try Windows 7 and made the necessary preparations. I am trying to build a dual boot system with the OEM 32bit Vista Home Premium and 64bit Windows 7. My machine is far above the specs and I have 3gb ram.

I burned the image twice after reviewing the other posts in the forum. I burned the first on at 8x and after reviewing prev posts I burned again at 4x. Both freeze at the expanding files 0%. The first one would hang for hours until I told it to cancel. The new one hangs for a few minutes and then gives an error that there is a corrupt or missing file.

I also read that this may be a result of ACHI but my bios does not allow me to disable.

I would appreciate anyone's thoughts and hope I can get pointed in the right direction.

Thank you all in advance.

Vista Home Premium
Tried that too

Thank you for your quick response. I tried running one stick of ram in the two different quantity options and it did not resolve the issue.

Any other ideas?

Burn the image at the slowest speed possible (1x)
That solves the problem

Where did you get Win7? Check the ISO Hash against official HASH. You may need to download again.

Next use ImgBurn to Verify DVD: Load ISO to make sure it says "Bootable" in text at left, then insert DVD to Verify against DVD. If necessary, burn another DVD using ImgBurn at 4x as it never fails.

Are you using a cheaper quality dvd? Try burning on a 'name brand' one. I had that problem using generic blank dvd+, I burned on a higher quality I think memorex dvd+ and it worked just fine
