I must have used some other command then, which resulted in my first disk MBR getting over-written ... strange. :-/ By the way, does the fact that NTLDR is on my first disk, while FreeBSD (and hence its MBR boot0) is on my second disk complicate matters? I mean, you mention boot0 will modify my partition table to reflect which OS was booted last -- will it by any chance modify the partition table on the first disk and hence mess it? -- Rakhesh rax@rakhesh.com
