I have an old Dell laptop ( Inspiron 2650 ) I am trying to dual Boot XP Pro and Ubuntu 10.10. Windows XP Boots fine as it stands and the 40 GB disk is currently partitioned as:


 /dev/sda1  ntfs   10962 MB
 /dev/sda5  ext4   27798 MB
 /dev/sda6  swap   1244  MB

I am not sure on which partition to install the linux Boot Loader.

I assume I do not want to install on /dev/sda1 since it will mess with the Windows MBR? Will I be able to dual boot if I install in /dev/sda5? Or should it be installed on /dev/sda?

  • Windows has no MBR, the disk has an MBR. And the disk is /dev/sda (no 1 at the end). – Hennes Jul 10 '16 at 15:55

Yes, install it to MBR, then you can chainload XP...this will work out of the box on 10.10 with grub2 and should be automatically detected.

MBR is always /dev/sdx, no number so in this particular instance it's /dev/sda

  • Is MBR on /dev/sda or /dev/sda1 in this configuration? – mozzer Dec 8 '10 at 17:51
  • edited to reflect where the mbr is located – RobotHumans Dec 8 '10 at 18:00
