How do I remove the BSD bootloader? - PC-BSD Forums

HXC · #1 08-29-2006, 07:48 PM

I have trouble getting the BSD bootloader removed. When I try overwriting it with grub or lilo they both give errors. I also can't boot into windows anymore. How can I cleanly remove the bootloader so that I:

1 Can boot into windows

and/or

2 Install grub/lilo in the mbr

Thanks in advance!

Use your WinXP CD. Start from CD, use Repair and use commands fixmbr and fixboot but after that you will have no access to bsd partitions!

After that you need to install GRUB/LILO.

Personally I'd just forget about the WinXP disk and install GAG < Sweet boot loader :-)

I tried these commands in the past. This didn't really wipe the FreeBSD bootloader. (I needed win98 to format my entire partion, before I could install any other OS, including Windows XP). Gag is really nice, but I don't have a floppydriver anymore

Edit: I see Gag can also be installed from cdrom

, still I would like to know how I can cleany remove the BSD bootloader :roll:

Seek for the tools "MBRWORK" and "MBRTOOL". You can find it on UBCD - Ultimate Boot CD:

from DOS:

Code:

fdisk /mbr

or from FreeBSD livecd:

Code:

dd if=/dev/zero of=/dev/ad0 bs=512 count=1

It depends on place, where bsd boot loader is. If it is on the same partition where BSD is, then just use FDISK and change active partition, It wont be removed but disabled and you will get a backup bootloader.

Technically it will do the same, tad FIXMBR does

Never tried this one , but is .. emm .. 'roll-back solution' for problem "i installed win after bsd. how to get my boot loader back?"
