grub on usb hd

[grant937]

While installing Mint KDE CE on a USB HD the option of installing grub on (HD0) was listed during the process. I have a Fujitsu notebook notebook with Vista installed on the notebook HD and was wondering if grub will be installed on the USB HD or the notebook HD MBR.

Thanks

(HD0) is your first internal hard disk not the USB one (it may be (HD1) but you can use /dev/sdb)
your USB one should have mounted and you could see it if you run the df command in a terminal.
once you see the usb disk gets its /dev device number to use eg /dev/sdb and use this as the mbr device.
in advanced replace (HD0) with /dev/sdb.

hope this helps

thinking about it some more it maybe a bit more complicated.
when you boot off the usb HD it may be seen as HD0 or /dev/sda.
but when you boot off the CD/DVD it sees it as say /dev/sdb.
so I expect you will have to install to the usb HD and setting grub to its mbr and after its installed remount it do a chroot and change grub to make it look at /dev/sda when it boots off the USB (itself).

Im sure there is a howto/tips and tricks on the site somewhere. it has been before.
