Cant boot windows 7 after Ubuntu installation

[Elio81]

Hi guys, thank you for the welcome message.

i have just installed Ubuntu 10.10 on a pre installed windows 7 system. Ubuntu is working really well but the only problem is that when I try to boot into windows,

I get the windows sign and then I get a black screen and windows does not load. It seems to be an easy problem to solve because I can actually boot windows 7 in

safe mode with no problems at all! The problem is there when I try to boot windows 7 normally. To be honest I only need windows for a project that uses MSQL server and

after that switching to Ubuntu forever!

Could be you need to do a chkdsk you can initiate it from the safe admin command line, or just the command line choice with a f8 prompt
chkdsk /r

At some point in this process in the Ubuntu terminal run
sudo update-grub
this rewrites grub each time it is run to align the boot, you might just try this first.

There is a script in my signature we use as well for analysis of the setup, run it and post the text in code tags if needed. code tags are generated by clicking on the (#) in the reply panel paste the text between.

ok i did that and the result is below. Still I could not boot windows unless in safe mode. Sorry just saw the rest of your post, I will do what you asked and reply back.

So if you run the chkdsk you want it pointed at the correct partition it looks as though sda1 is probably a boot partition.

Vista/7 CHKDSK
chkdsk [drive] /f /r
chkdsk C: /r
/f : Fixes errors on the disk.
/r : Locates bad sectors and recovers readable information.
Note If you specify the /r option, the /p option is implied. When you specify the chkdsk command without arguments, the command checks the current drive with no options in effect.

if i where you i would backup my files. when i installed Ubuntu on my laptop with win7 in dual boot, win7 crashed hard i lost a good bit of stuff. so if you can access your files back 'em up just encase.

thank you for the advice, I've already backed up all data to an external drive

[wilee-nilee]

So the script looks basically okay for it likely being a chkdsk needed, since your backed up that is what I would do if it was me.

There is this though

I don't see any overlapping partitions this is a large partition and I'm not sure what the answer is here.

im running chkdsk at the moment, its taking a bit long so i will be back with the result asap.many thanks. by the way is this the right place to say how much i hate myself for never using ubuntu until now. what a waste of money on windows all these years.

The /r takes a long time, I think Both OS probably have their uses, I didn't really need my W7 setup and the MS word 2007 I have until I turned in a paper on line that just wouldn't work and render the .docx correctly otherwise.
