Batfink: After trying to get OS Selector to recognize a copy and it failing on me, I came here and realized I was doing lots wrong. I read your posts in other threads and tried setting it up like you described but I keep running into problem, please help? I'm now trying to set my computer up like yours. I would like two of the same operating systems, Windows XP. One as a main and one for use when I'm tweaking things. I already have the operating system and I don't want to reinstall windows to get this to work. I first backed the OS up using True Image 9. I then wiped the entire hard drive clean, and then proceeded to repartition it. I partitioned it similar to the way you have yours set up, 1.5 gb for the primary partition and I placed AUTOEXEC.BAT, CONFIG.SYS, BOOT.INI, IO.SYS, MSDOS.SYS, NTDETECT.COM, and ntldr on it. I then restored the image I made with True Image to the second partition and left it as a logical partition. I then did the same for the third partition. The Boot file on the first Primary Active Partition, reads as follows. After doing all that I install OS Selector on the first and only primary partition, and then attempt to load it all up. OS Selector reads the BOOT.INI file and finds both XP Home, and the one I named XP tweak. I then followed your instructions further and removed folder protection on all the drives and hid the Partitions from each other. But here’s where I run into a problem. Trying to load the OS’s up they load up and get to the log in screen, typing in my password and immediately it says logging off. They won’t get anywhere past the log in screen. I thought maybe it was a problem with the Acronis Backup Image, but no such luck, I’ve tried doing this eight ways to hell now and still run into problems, mostly the one I described above. I actually did manage to get it working once, but Windows asked me to reactivate so I scraped that, I should have probably reactivated because that was the only time it got past the log in screen. But now I can’t duplicate that result. I’d appreciate any help you can provide, or anyone who may be able to provide help for that matter. Please.
