I want to use this particular windows installation, as it has some software on it that activated online and i'm probably only entitled to one installation of the software. Reactivating software would be an issue. I'd prefer to keep the XP Installation that I have. When I resized the partition I suddenly got this windows genuine advantage problem.. where it asks me to activate windows.. I could try activating it but i'd like to get rid of the message by not having to activate it! It doesn't say it's not genuine, it just says "This copy of windows is not activated" My MBRD is Intel 410PT. I got out a USB dos boot disk, and I got that OEMBIOSTEST-USB.7z file, understood what's in it, and I copied XPOEM.EXE(all I needed) onto my USB dos boot disk. I ran XPOEM.EXE from my USB DOS BOOT DISK, it ran fine, but it said "None of the 126 Contained OEM BIOS Sets will preactivate this system" this is all so I can get an identifying code to know which set of 4 files to use with the OEMBIOS tool. What can I do though, to activate it, if XPOEM.EXE is giving me that message? I don't know whether this matters, but this Windows installation was installed on a Dell (Which I have), though the dell has an issue booting USB and CD! So I moved the hard drive to another computer(different MBRD/chipset), and (amazingly) Windows XP managed to load on it. I don't know if that's relevant 'cos I don't know what XPOEM does/how it works/what it reads/needs/assumes. Or what's going on! Perhaps some here can throw some light on this problem?
