View Full Version : [ubuntu_studio] Boot Loader Problem after upgrading to 9.04 and messing with Grub

June 10th, 2009, 05:16 AM
Ok so I am in deep trouble with my laptop. Let me try and explain the situation as well as the problem as clearly as possible.

This is what I had: Windows 7 and Ubuntu 8.10 both on my 60GB harddrive. Ubuntu had like 35 gigs or so and the rest was Win 7. I used to get the Grub Bootloader menu (pressing escape while booting) to select what OS I wanted to boot into. Hadn't booted in Ubuntu for a long time because there were some problems with it (due to a skin/theme file I had downloaded that went bad and didn't feel like fixing it).

So I was content with Win7 Beta. Then I saw Ubuntu Studio 9.04 and thought that I should give it a try. Downloaded the iso (but turned out to be the alternate CD) was not an easy install like a LiveCD.

I went crazy with the partitioning of the hd then:- Used the Ubuntu 8.04 LiveCD and started Gparted. In there I had couple partitions (ext3, ntfs, swap and one other I don't remember). So I erased the ext3 and the 'one other' completely and resized the Win7 to give it more space (35GBs) and had unallocated space of 25 GBs. I renamed the unallocated to be a ext3 so that I can install Ubuntu Studio 9.04 on it. And then started with the installation of Ubuntu Studio 9.04.

After the installation:- The Grub bootloader now does not show the Win7 OS, so now I can't boot into my main OS. It is there I know because when I boot into the Ubuntu Studio I can access the 35 GBs of the Win7 drive from >Places.

1) How do I get the Win7 back on the GRUB so that I can boot into it?

Also, (2) since its been a long time since I've messed with Ubuntu I don't know how to get my Wireless running on it. Any help would be great. (3) when installing via the alternate iso dvd, at the end it asked me what softwares to install (2d/3d photo editing, music etc) and I didn't read the bottom instructions line properly and figures If i just press enter on all 3 groups I would get all of them (I want all) but stupid of me, pressing enter on the first option (2d/3d softwares) obviously skipped the rest and the installation was done. How do I get those other packages???

Thanks for your help, I really appreciate it

run this in terminal
sudo fdisk -l then post the output here.

also run in terminal
gksu gedit /boot/grub/menu.lst and post that output here also. BTW those are lowercase Ls in those commands

Can't help with wireless as I don't use it.

You might try adding this to the end of menu.lst:

title Windows 7
root (hd0,2)
chainloader +1

Also, try removing the boot flag from sda1 and adding it to sda3.

June 10th, 2009, 07:43 PM
will try that....

but how do i the boot flag?????

June 10th, 2009, 08:23 PM
Ok so I added that last bit in the menu.lst and tried to boot into win7 but when I selected win 7 from the grub menu it said that BOOTMGR does not exist press ctrl alt del to restart or something along those lines. Then I put in the live cd of ubuntu 8.04 that I had and started gparted. In there I made sure that the boot flag is checked on the sda3 and not on sda1 (which is how it was from the beginning)

June 10th, 2009, 08:25 PM
gparted on the ubuntu live cd will do it. You can set the boot flag from it by right-clicking in the Flags column of the partition and selecting Manage Flags.

June 10th, 2009, 08:54 PM
Did that doesn't help

June 10th, 2009, 09:09 PM
I really need to boot into win7 as there is some things I have to do in that os. Please someone help

June 10th, 2009, 09:11 PM
This small change may help:

title Windows 7
rootnoverify (hd0,2)
chainloader +1

Otherwise, from the results of fdisk -l, it would appear that something is amiss, because there is no sda2:

sudo fdisk -l

255 heads, 63 sectors/track, 71113 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda4 6818 7113 2377620 5 Extended
/dev/sda5 6818 7113 2377688+ 82 Linux swap

When you run gparted, what is it showing as to partitions? Also, you might post a screenshot.

If nothing works, you should be able to boot from your windows disk, select recovery, and fixmbr. That should at least let you boot directly into windows, and you can reinstall grub if you want to run linux as well.

June 10th, 2009, 09:26 PM
I can't really post a screenshot since I'm accessing the Internet via my iPod only. But this is what the gpartition displays:
Sda1 22.93 gb ext3 (no flags)
Sda3 29.29 gb ntfs (boot flag)
Sda4 2.27 gb extended
- sda5 2.27 gb Linux swap

June 10th, 2009, 09:51 PM
Again, interestingly enough, sda2 is missing.

Did you try changing the lines in menu.lst to:

title Windows 7
rootnoverify (hd0,2)
chainloader +1

June 10th, 2009, 09:54 PM
When I insert the win7 disk I select the repair ur computer option. It detects that there is a problem with start up and asks me to repair n install. Don't c a option for fixmbr. And after restarting it doesn't work

June 10th, 2009, 10:04 PM
Good news guys it's working. All I did was booted with the win7 cd selected repair install and opted for the startup repair. It automatically fixed the prob and now I can start win from grub without any problems.
Thanks for all your help.

Also, how do I get the wireless working on my ubuntu studio os. And I don't have all the programs that come with the os.

June 10th, 2009, 10:09 PM
Glad it is working. I guess win7 uses something different from xp's fixmbr to do the same thing.

Don't know about the wireless, but you can find lots of apps via Applications/Add/Remove and synaptic.
