how to boot a mbr?

[ant1688]

dear all,
I have 2 harddisks.
The grub is installed in the mbr of 2nd disk. the plop boot manager is installed in the 'boot.ini' in the 1st harddisk.
The plop has boot items of each partitions, but no mbr option to boot.
I hope to boot the grub in the 2nd disk, how to?
thanks!

hi,
do you ask because of a rescue purpose? the boot manager is not designed to boot a mbr of another hard disk. there is a workaround to boot the mbr with the pop boot manager, but user interaction is required.

thanks for quick reply.

The thing is my bios doesn't support to boot from second hard disk, while the linux does not encourage to install grub in partition and I like to leave the mbr in the first harddisk not changed.

so I am thinking to install the grub to a patition of the 2nd harddisk.

by the way, what is the workaroud boot manager?

I used smart boot manager from floppy, it is able to boot the mbr on the 2nd hard disk, but it doen't support to boot usb as plop.

I haven't found a boot manager which includes all desired functions: boot from mbrs, usbs and partitons.

best regards,

whats the partition layout of the second hard disk? i only need to know how many primary and extended partitions you have.

it is an ubuntu in the 2nd hard disk.
the patition table:
/dev/hdb1 /boot
/dev/hdb2 /
/dev/hdb5 swap


in ubutu I use 'grub-setup --force /dev/hbd1' to write grub in the 1st partition today, the plop in the 1st hard disk is able to boot the ubuntu now.

THANKS!
