Windows 7: can't do clean install from Vista 32 to Windows 7 64

We are all trying to help. Lets be sure we understand the language. By clean install, did you chose format from the advanced options?

See if you can find these - the last entry should offer a good clue:

C:\$WINDOWS.~BT\Sources\Panther\setuperr.log

C:\$WINDOWS.~BT\Sources\Panther\setupact.log
C:\$WINDOWS.~BT\Sources\Panther\miglog.xml
C:\$WINDOWS.~BT\Sources\Panther\setupapi\setupapi.dev.log
C:\$WINDOWS.~BT\Sources\Panther\setupapi\setupapi.app.log
C:\$WINDOWS.~BT\Sources\Panther\PreGatherPnPList.log
C:\$WINDOWS.~BT\Sources\Panther\PostGatherPnPList.log

If you are determined to get 64 bit install, then shrink your 32 bit installation in Disk Management and format a test partition to continue trying to install 64 bit from booted DVD.

When the install bluescreened, did you try entering Safe Mode by tapping F8 during reboot?

Also, did you try booting into the Windows 7 DVD Repair console to select Startup Repair and run it repeatedly to try to get Windows 7 started? Did it find an OS to repair when doing this?

SIW2, where would he find these logs and when? He bluescreens out at booted 64 bit clean install finish. Only succeeded at 32 bit in-place.

Rich - I appreciate it. Yes, I've tried both formatting & without formatting.

SIW2 - as Greg said.

Try SATA controller set to AHCI. If booted install will still not complete, try IDE.

I'm just off out & will try it when I get home & let you know. thanks!

u have to do 2things.it may solve ur problem.
on vista,with all drivers installed.check with MS compatibility check software,that does ur pc supports windows 7 x64 or not.
2ndly.if it supports,then go to BIOS and turn SATA mode controller to AHCI and then do clean install from disk,it should solve the problem.

else than this,u might try to install from usb flash disk,simply copy all cd stuff on usb and boot from flash.it will install much quicker too.

I've already checked and yes, my pc supports Windows 7 64 bit.

I'm probably being really stupid here but I can't see where in the BIOS I can change the SATA mode? The only option under SATA is "auto" or "large".

I don't know how your BIOS words it, but look at all the settings until you find options such as non-raid, AHCI, and RAID.

I looked for them but couldn't find them anywhere. This is the first time I've gone into the BIOS on this PC & I've always seen those options on my other PC's but can't see them listed on this one. Only the option to change between auto or large. If it helps, it's an ASUS motherboard with Phoenix BIOS.
