Can't boot either Ubuntu 10.04 (64-bit) or Windows7

Asked by David Day

I have a dell laptop with an Intel Corei7 processor and 6 GB Ram. I did the partition to install Ubuntu 10.04 alongside Windows7 and on the first reboot the Grub menu appeared and I booted Ubuntu successfully. The second time I rebooted Grub again appeared normally and I booted in Windows7. WIndows7 did a disk check, but I didn't see any problems when running it. On the third time I rebooted, however, I don't even get the Grub menu. I the following error:

no module name found
Aborted. Press any key to exit.
(upon pressing any key)
-(some information about the patents on the computer)
PXE-E61: Media test failure, check cable
PXE-M0F: exiting PXE ROM
Operation System not found

I am able to boot in Ubuntu only with the disk in. This is a very serious problem for me; I would like to either fix this or undo the damage quickly. Thanks in advance for your help.

Here's what I would do:

1 - Open BIOS and check if bios recognizes your hard drive
2 - Open boot manager and boot from HDD
3 - From those error messages, it means that something is wrong with your HDD
     - Check ALL Cables
     - When you installed Ubuntu, did you make a new partition? Sometimes if your original partition is the whole drive then changing it later will screw with the software because the original (in this case windows) thinks it should have more space than it does, and Ubuntu will think that it has the whole partition meanwhile it may be overwriting a layer or windows files. Basically Ubuntu gets installed, overwrites some windows files, making windows inoperable, and ubuntu now has some random windows files it doesnt recognize.

Anyway, I would re-setup the drive, delete the Ubuntu partition, restore the windows partition to it's old original state before ubuntu. And try running windows. Hopefully that will fix windows.

Next, if you have your windows 7 disk, boot that off the CD and create a partition using that.

Install Ubuntu on the new partition.

Thats all I can think of,
Hope it helps,

Can you help with this problem?
