No OS Detected.

[Will Murray]

I am installing the latest version on my laptop.

The installation seems to go smoothly, I am using the whole hard drive on the laptop as the system drive. After installion finishes ubuntu starts (I am assuming it is running straight from the install disc). After removing the disk and restarting the laptop, it claims I have No OS.

SATA 80GB HDD
GeForce Go 7400
Intel(R) Core(TM) 2 CPU T5500 @ 1,6 GHz
1 Gb RAM ( 2 512mb sticks)

BIOS Version: Q3A24

Will update with other hardware stats when I find them.


Thank you in advance for any help.

Check your bios if you boot from your harddisk?

Wenn booting you will see grub, press "esc", you will come in a menu(grub), then press "e" to change the harddisk number.(the first ubuntu)
hd0,0
hd0,1
hd0,2
hd0,3
hd1,0
hd1,1
etc, first number is harddisk number and second number is partition number.
After changing the number then press "b" to boot, if it does not work try a different number.
It is possible that because of usb things connected that the number is wrong.

If you do not have grub, then install with "super grub" grub again, this is a bootcd you can download.

Thank you for the help but I am still having trouble.

I have no external usb devices connected, the only boot device is my system drive.

I used super grub but I only seem to get errors with that, is it possible that my hardware is not supported? thanks for any help in advance.

Puneetsoni, how about booting your Live CD, downloading the attached "boot_info7.sh.txt" file to your desktop, open a terminal (Applications > Accessories > Terminal) and do:

sudo sh ~/Desktop/boot_info7.sh.txt
That will create a "BootInfo.txt" file on your desktop; please attach that to your next post, or simply copy/paste the contents to your next post. That will help clarify your setup and what your problem might be.
