[Bug 111731] Re: install to an usb disk does not work

[Michal Suchanek]

grub version has nothing to do with this.

This is installer bug.

BTW what information do you lack to diagnoes and fix this?

TEST: put and internal disk and an USB stick into a PC. Install on the
USB stick. Remove/disconnect the internal disk. PC should be bootable.

Title:
  install to an usb disk does not work

Status in “ubiquity” package in Ubuntu:
  Fix Released

Bug description:
  Tried installing Feisty to an USB disk.

  - the disk is offered n partitioning and can be set up for
  installation. However, the installer offers to install grub on (hd0)
  which is the internal drive.

  - the installed grub is configured to load kernel from (hd1,1) but the
  USB disk is (hd0) when booting from it

  - when I boot from the USB disk and try to redetect grub drives the
  disk map is still wrong. It assings (hd0) to the internal drive and
  (hd1) to the USB drive

  - when I edit the disk map and reinstall grub I also have to change
  the root in menu.lst

  After that the install worked except hibernation. Hibernation probably
  turns off USB and I get loads of messages about rejecting IO to a dead
  SCSI device.
