Hi Everybody
I have a PC that I built a couple months ago. I want to do a dual boot between Windows 7 and Ubuntu 11.10. The problem comes after I load Ubuntu, it seems to boot ok it then comes to the login screen I type in my password and it does not go any where.My Mother board is a Biostar N68S3B Processor is AMD Athlon II x4 630 2.8 GHz Socket is AM3 Chipset is GeForce 7025/nForce630a
P.S. I can not boot in to windows at all either. I was told that Ubuntu might not be compatible with the drivers, if so is there a fix for this out there.

Thank You
Woodman

Wait, Windows is also unbootable? If both OSes lock up and won't boot that would be leaning more towards a hardware issue than software...

Are you able to switch over to a different terminal when Ubuntu get's stuck at the login screen (Ctrl+Alt+F2)?

Welcome to LQ.

We can probably unpick this, but we need detail - loads of it.
What happens exactly when you boot windows. I don't want a line, I want a couple of sentences, & exact error messages.
What happens when you boot linux. Mention stages that work, which login screen are you stuck at? Does X boot? If you hit Ctrl_alt_f2 what do you see? If a console, can you log in there?

Lastly, just to check the hardware, boot from an install cd. Does that work? you don't have to install anything.

when you have problems with loading/booting both a linux distro and windows, that is normally a sign that there is some hardware issue.

BTW, I've run a GeForce 7025/nForce630a chipset board witha few linux dirstros, no driver tweaking needed.

I can not boot into windows. If I try to reboot it goes straight to Ubuntu I type in my password and the screen goes to that purple screen and nothing happens.I have tried different to escape key to try to get out of everything, also Ctrl+alt+del and still nothing worked. So I ended restoring the PC Back to Windows 7 from a clone I made with Clonezilla. I do want to have a dual boot machine because there is so much that I want to try out in Ubuntu. I have used the Live CD to try Ubuntu 11.10 and it works fine. Just to let you know one more thing, before I installed Windows 7 I tried to install Ubuntu 10.10 it installed no problem except that everything I did in it would lag badly. ex. If I went on Firefox and brought up a page and went to scroll down it would step it's way down the screen, but the graphics was fine. So I thought it might be because I did not do any updates yet. When the updates center came up it said that 11.10 was out and I could download that with the updates, after the updates where done and the computer restarted the screen went back and I could not get into anything. I did install the Ubuntu 11.10 on an older computer for a friend with the same CD and it works just fine. So I have no clue what to do with it anymore. If this helps please let me know.

Thank You Woodman

Hi,

It installs, so you have disk writing (my old 630a chipset needed a sata driver module patch first, but that was a long time ago(asus m2n)).

It could be bad memory, have you done a complete "memtest86+"?

From what I remember, GNU/Linux and M$win have different requirements, what may work in win may not with linux.
I think GNU/Linux has tighter memory constraints than M$win, if I remember correctly.

Generally, I do a memtest with The install cd-disk, like Mageia-1, in my case.

The other questions above are good points too! (, at least you have the sata drivers...lol)

Hi
I have a 4 gig stick of Corsair DDR3 ram Model XMS3 if I do the memtest86+ what do I look for when it is running or when it is done with the test.

Thank You

Hi, you'll get errors, generally shown in red.

If it passes all the tests once, your probably OK for general use.

It takes time, be sure to check that the total memory is available, and wait.

tip. I generally skip to test 6,7,8 & 9. Run them individually if you like.

imho, if it passes test 6, it's probably fine.

I got errors once, and found that it was a bios update that was required for the chipset memory controller. edit, those errors showed up pretty quick.

Regards Glenn

Based on this
1. Windows didn't work probably because it wasn't in grub.
2. Linux had some graphics issue and another issue we are not at the bottom of.
3. None of this matters because you have overwritten them.

Close the thread (Mark it solved and post again if you hit trouble installing linux.
