I downloaded UBCD4win and successfully created a CD. It will boot OK off of one of the laptops, without any errors and is repeatable. On another one (once again repeatable), I receive an error "nu2menu.exe not found", after which when I try to run Joshua's pre-shell (UBCD4win-auto) I get "Run-time error '6': Overflow" and then a blue screen where I must hold the power button. Yet another identical (ie. model numbers are identical, BIOS and BIOS version identical, I'm checking on DVD drive firmware) machine boots the CD fine, but when trying to load RocketDock.exe, it will claim "not a valid win32 application" and just now, when trying to run it from an Explorer.exe I get "The application failed to initialize properly (0xc0000006).
I have tested the RAM with Memtest86 version that comes on UBCD4win 3.5 and it reports no errors (what else does UBCD use, hard drive?, could memtest not be testing all my RAM? It reports 3GB which is what they have.. Windows 7 home boots on all the machines fine and runs fine, and there is no indication of a hardware defect, although it seems the only possible explanation based on the tests I've run. I've burnt 3 different UBCD4win's, 2 CD's and one DVD, they all behave the same so please don't waste the forum's time with suggestions about media and burning software (I see people suggest this when they clearly have no idea what they are talking about).
Any ideas are greatly appreciated.
