Installing Dual Boot Ubuntu/Vista


Installing Vista on my PC has convinced me I need to start converting over to linux. If only things were that simple.

I have tried on multiple occasions to install a dual boot on my machine, and all have failed. I have an Asus p5e3 deluxe/wifi-AP@n motherboard. The mobo has the Intel ICH9R chipset that I am using for a RAID0 array for one of the drives.

All of my hard-drives are SATA

Hard-drives 1-2 (Raid0) 75GB each @150 for the raid
Hard-drive 3 (non-raid) 750GB


This has been the source of my headache. Ubuntu has been unable to recognize the fakeraid, so I tried to install Ubuntu on the other hard-drive. I can not seem to get the MBRs to play nice together, and I get a GRUB error 21. I have failed in fixing this problem, so I have decided to take another approach...

What do I have to do in order to "correctly" install a dual boot of linux the first time? In the past I have tried with a 64-bit version of Ubuntu, but I am not attached to that distro. I am willing to install any distro that will actually work. My only preference is that it is 64-bit compatible.

Hopefully this is the place for answers, because I'm about to give up on Linux (for this PC anyway).

Have you tried going into BIOS and making the Ubuntu drive the bootable one?

First I will presume the ubuntu disk is good (no doubts). If after you try jay73's advice please give us more info such as what you have tried and which hd windows is on and which hd you would like ubuntu on. If you can bring up a live cd give us 'fdisk -ls'. Do you have your cd/dvd player first in the bios boot order?

Yes, I have tried that and I still get the same error.

I have since uninstalled Ubuntu and am back to where I was. One Vista OS.

Like I said, I do not wish to continue down this dead end of trying to get linux fixed after a bad install. Instead I would like suggestions on what distro and how to install properly in the first place with this setup.

I think the problem was in the MBR, mainly it's pointing to the second disk (which should be the 3rd disk, i.e. not the second of the raid).

some more info...


Vista currently resides on the RAID.

I don't care where linux goes, I just want it to work.

I tried installing ubuntu both on the raid and on the other drive. I had better success on the other drive since I was having a terrible time getting ubuntu to play nice with the fakeraid. I was never able to boot either.

When I installed Ubuntu on the second drive (non raid), I could install it but never boot into either windows or linux. This is where I got the error 21 at GRUB 1.5. I tried using Super GRUB to fix the problem, but got nowhere.

I am sorry but not sure if switching distros will solve the problem.

Is there perhaps one that can better handle the Intel raid Chipset? Seems like Ubuntu was not equipped to handle it.

Are you sure that those drives are running in AHCI mode, not in IDE mode?

If you find it doesn't make any difference, then Fedora may work. Its installer has options to set up a RAID but whether it will work for any type of RAID, I couldn't say.

The drives are in RAID mode. I was going to try changing that to AHCI, but I read that altering the setting after an OS was installed caused issues.

I see there is a newer version of Ubuntu out (I have 7.10). I'll try that, and also give Fedora a shot.

No problem, RAID is what it should use. My mistake. AHCI vs IDE won't make a difference. Maybe you should try using labels to identify your partitions. They tend to be more reliable in complex set-ups.

well, good news is that Fedora worked great. It recognized the raid right away and worked perfectly. So much better than screwing around with Ubuntu, so thank you for that.

Bad news is that one of my Raid drives failed in the process, so now I have to reinstall everything again...I have been looking for an excuse to buy a solid state drive anyway. Also, it is a good thing my motherboard has a Splashtop browser built in (what I'm posting with atm). I'm sure I'll be back if I have more problems.
