View Full Version : [ubuntu] Dual Boot Issues

May 15th, 2008, 10:45 AM
I realize that there is an overwhelming amount of issues running around here, but any help would be appreciated. I'm a newbie so forgive me.

I just recently reformatted my hard drive and installed xp, soon after hardy heron came out so I decided to install that as well. I've split my 500gb hard drive into two partitions one for windows, and one for linux, and I also have another hard drive that I use solely for media.

The problem is when I start my computer the dual boot program (grub it's called?) doesn't load, instead windows loads up as if ubuntu had never existed. I've looked around the forums, and there are talks of re-installing grub, and doing some other things but I'm not sure of anything.

Here's any relevant information that may help:

Microsoft Windows XP
Ubuntu Hardy Heron
Intel DR33TL Motherboard
Intel Q6600 Processor
4GB DDR-800
1 x 500GB
1 x 120GB
No Graphics card.. (for now :P)

sudo fdisk -l

Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x7ee57ee5

Device Boot Start End Blocks Id System

255 heads, 63 sectors/track, 60801 cylinders

/dev/sdb6 59583 60801 9791586 82 Linux swap / Solaris

Thank-you! (I got the above information through the LiveCD don't know if it is still relevant..)

If you installed in this order - ubuntu, xp - you are right you need to reinstall grub. Not painful - you'll need you're livecd adn this page should do you nicely

Did you partition before installing anything? Did you install Windows first in sda?

May 15th, 2008, 10:15 PM
I had Windows installed first, and then through the partition manager in Ubuntu I partitioned the 500gb hard drive around 50/50 then installed Hardy Heron in the newly made partition. Thanks for replying guys :P

I would like to know if you achieved dual booting through Grub with that method of partitioning.

i too am having the same issue. i am trying to install 8.04 and have dual boot to XP media center (my OEM OS). an i installed it but i never get grub, and i have reinstalled it. my specs are:

Dell E-510
1 X 160GB SATA II HDD - this drive has; windows OS partition, recovery partition, and dell utility partition, is also where i put 8.04

could it be the Dell partition(s)?

also in win xp i have found the Boot and recovery options TXT (under system properties, advanced, start up and recovery, manually chance options), here they are

"[boot loader]
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Media Center" /fastdetect /NoExecute=OptIn"

as you can see it looks at only partition 2 (as default) on the HDD can this be changed or does something else need to be done. Does this matter?

Well, that is precisely the issue here. I can not reach the grub menu at all, as I mentioned before unfortunately when I start up it just goes straight to windows, and ignores ubuntu. Last year around this time this is how I had Gutsy installed, the only difference was I didn't have the 500gb hard drive, but instead split the 120gb hard drive. So I know it can work, but I'm not too sure how to go about it, thank-you for helping me with this.

The reason I asked is that you have to use the Vista partitioner. You cannot use the Ubuntu CD to partition; otherwise you'll never achieve dual booting through Grub.

May 15th, 2008, 11:58 PM
Why is it that I did not have to do this with Gutsy? Because last year I just let the live cd installer just split my hard drive and install ubuntu. Sorry, I'm just trying to understand the situation a little better. I use Windows XP, so would I just format the partition that the live cd created and install ubuntu in there or something? Sorry if this doesn't make sense..

If it's XP, you should have no problems. I thought you were using Vista.

May 16th, 2008, 12:03 AM
Ah for once I wished I use Vista, haha. Well this is quite unfortunate..

Try changing the boot order of the hard drives in BIOS.

May 16th, 2008, 04:51 AM
Sir, I do believe that we have fixed the problem. I changed the boot order of the drives, and I was able to boot into ubuntu. This is great! I appreciate the time, and effort of you helping me with this.

You are welcome. Good luck.
