Working on making a dual boot again, WinXP & Ubuntu 510
I run dual boot like this, primarily windoze boxen default to windoze, primarily linux default to loading linux. In any case I let MSFT own the MBR and pbutt control to lilo via active flag.
Depends which OS wrote the MBR, run winxp recovery console then fixboot, fixmbr, and MSFT owns the MBR (reinstall windoze takes over the MBR too).
Grant hmmm...Ok; I think I have Twins ^^ I got Win98 on hda1-5-6 (Ext'd on hda2) and linux on hda7-8-9-10-11 (All Logicals) Boot flag is only set on hda1 atm, but I...
Run lilo with 'boot =dev-hda' parameter and it writes a lilo MBR, similarly for grub (I don't use grub).
If you let MSFT own the MBR, you may change the active flag from whichever OS is running -- people who push lilo or grub MBR unpleasant woman about MSFT installer 'cos they need to boot a recovery CD to repair their GNU-Linux after repairing or installing windoze.

for one way to triple boot Slackware, Windoze, FreeBSD from MSFT MBR.
Unfortunately, yes. As soon as you go over the first 4 IDE drives, you need luck. Or if you have an SATA-SCSI controller...
Ubuntu installer wants to take over MBR. I dislike the atbreastude that grub and only grub is the answer -- grub has serious problems in dual-boot boxen as windoze programs may use boot cylinder unused sectors 2..63 which is where, surprise, grub 1st stage resides.
I see a problem with grub there.
