I installed ubuntu 12.04 by formatting the drive that had windows 7. The installation went fine but after I rebooted It asks me for a windows 7 disk repair disk and doesn't even look to recognize any other system. I entered the try ubuntu mode and the drive is there. The amount of space in the drive is 120GB and the drive has 119,24 in ubuntu. I can't find the drive that windows 7 use to boot anywhere. I runned boot repair but that does not seem to be the case it still does the same problem. I have a desktop.
I installed ubuntu but the boot seems messed up. I still sees windows 7 as a boot option and ubuntu doesn't boot. How can I reset the whole boot system in some way?

  • It's all guesswork without more information. Download the Boot Info Script (sourceforge.net/projects/bootinfoscript) and run it from a Linux emergency system. The script produces a file called RESULTS.txt that contains lots of information on how the disk is partitioned and what boot loaders it contains. Post a link to the script here. – Rod Smith Dec 8 '12 at 4:42

Is this a laptop? Make and model?

It's always handy to have a Gparted live on USB or CD. It is probably part of Ubuntu Live CD as well. Fire it up and check that there's no other partitions.

The difference in sizes are because of GB vs GiB (Gigabyte vs Gibibyte).

GB  is 1,000,000,000 bytes or 10⁹
GiB is 1,073,741,824 bytes or 2³⁰

GB : 128 × 109 bytes = 128,000,000,000 bytes
GiB: 128,000,000,000 ÷ 230 = 119.20929 bytes (or 120 GiB)

Since GParted uses GiB the size is correct. 128 GB == 120 GiB or 119.24 GiB as shown in Ubuntu (a few bytes diff due to conversions) – and:

In some cases1 a few bytes are used by HDD as further firmware for the disk and S.M.A.R.T data: statistics modifications, bad sector map etc. (Meaning SMART is part of (all) HDD's but should do not affect reported size.)

  • I have a desktop. I have a 128GB drive but the Gparted shows only 120. – Atladica Dec 7 '12 at 19:43
  • You do not have any CD's, USB-disks etc. attached and it still asks for Windows 7 repair? And you specified to format/use entire disk on install? By "try ubuntu mode" you mean Ubuntu Live from install medium? – Runium Dec 7 '12 at 20:32

  • The MBR is messed up. It is weird and messed up that your install did not fix this. Using Boot-repair as well! One go would be to use GParted: 1. delete partition. 2. Install fresh. or try something in the lines of this: ubuntuforums.org/showthread.php?t=2001733 – Runium Dec 7 '12 at 20:49

The drive was so messed up that I needed to open a terminal and format it all the files inside even the boot history. That didn't work neither with Gparted nor boot repair.
