I have a secondary system that I put together with spare parts, but it doesn't have a CD-ROM. Here is my plan for getting XP on there. Let me know if I'm setting myself up for failure: Temporarily pop the HDD of that system into my main system running win7. It will get a drive letter. Let's say it's "F". First I will quick format the drive in NTFS: format f: /fs:ntfs /q Then I will make it bootable: bootsect /nt52 f: Then I will drag and drop the i386 folder from the XP CD to the F: drive. At this point I should be done with the XP CD. Then I will run f:\i386\winnt32.exe /syspart:f: /tempdrive:f: /makelocalsource /noreboot syspart:f should make that drive the system drive, tempdrive:f should make Setup use that drive for temp files, not sure if i need /makelocalsource, /noreboot will prevent my main machine from restarting The initial part of setup should complete, then I can just shut off my main system, pop the drive back into the secondary system, start it, and continue. Am I in for some real disappointment or what?
