I have windows 7 on a CD (and USB as well) which does not get recognized on my laptop (Samsung NP RV520). I can boot from both successfully on 2 other machines.
My boot order is cd, usb, hdd ...
When I insert windows7 cd, it is ignored and I get the choice to start the existing win7 installation in normal or safe mode or repair. (I have succesfully booted XP and I'll try Ubuntu tomorrow as well.)
When I insert windows7 usb, computer freezes on the "Starting Windows" screen with logo.
The existing installation of windows 7 freezes on the login screen, no matter what mode I use. It takes about 15-30 minutes for it to get to the login screen (and then it freezes) or it freezes before and shows a blank black screen, for hours.
I did install UBCD (Ultimate Boot CD) and tried to use boot managers from there, but all of them gave errors when I tried to boot from the windows 7 cd/usb, or the cd/dvd/usb did not get detected at all.
I tried following these instructions:
http://www.techdug.com/windows-7-install-cannot-boot-from-cd-code-5-problem-and-solution
But the cd/dvd drive did not appear on the list so I could not select it.
All I want to do is reinstall the windows7.
I also booted miniXP from Hiren CD successfully and ran a bunch of diagnostics tools. GMER showed 5 results in rootkit/malware, but I'm not sure how to interpret them.
Do these issues sound like something a virus in boot sector or MBR could do? That's a hunch I have, but I'm not a techie so I don't know.
Laptop in question had similar issues, according to owner, windows 7 was reinstalled at a service, and same problems started after a few days again.
I feel a bit lost at the moment, so I made this topic.
