Hi and Welcome !

Boot up Ubuntu and execute this in Terminal

sudo fdisk -l
df -h

Try re-installing Windows 7 Boot Loader and check if it boots up fine. It's really easy to re-install GRUB2 using Ubuntu LiveCD.
Follow instructions from here for Windows 7 boot loader reinstallation. ( I am not sure if instructions given on that link work or not. It's just a first google hit. )

[apverma13]

i have reinstalled grub 2 twice but no luck the same problem persists.selecting the windows entry restarts computer.

windows bootloader is working fine when it it not with grub2/

[devils casper]

How did you remove GRUB2? After removing GRUB2, did Windows 7 boot up by default or display any boot menu?

[apverma13]

i didnt removed grub2.

i used bootrex.exe/fixmbr command after booting with windows dvd that overwrited grub2 and windows is working fine.

after that i reinstalled grub2 from live cd but again the same problem. currently i m using windows but the data on ubuntu's partition is intact the day i find a solution i would switch on to it.

somebody on the other forum said that in sda1 :


Boot files/dirs: /bootmgr /Boot/BCD /grldr

might be causing the problem but even he dont know how. so if you can think of anything from that

[devils casper]

Let me try the same setup in my test machine. I will let you know soon.

[apverma13]

Let me try the same setup in my test machine. I will let you know soon.

thanks...you are doing so much for this problem.

[apverma13]

i m still waiting for a solution to my problem. anybody please help...
