Wont run BIOS

You have to recover your MBR looks like, but first you need to remove the hard drive and see if it will boot without the HDD installed then get back to me ok. Also sounds like the BIOS may have failed if it wont boot without the HDD installed. But first things first.

It sounds more like you haven't installed ubuntu correctly. Why do you think the drive is faulty, was it giving drive errors before you loaded ubuntu? Does the bios have s.m.a.r.t. disk checking enabled?

If you can get back into ubuntu perhaps by booting off an ubuntu disk you can check the disk - here's how How to run checkdisk
If not take the drive out get a sata to usb converter and run a disk checking utility on a friends machine
for example chkdsk space diskletter colon space / f
chkdsk e: /f

have you tried looking for a windows label on the laptop that will tell you what version of windows is on it

The fact you are seeing two hard drives is probably because it is partitioned. The hard drive you tried to boot from to repair it , that is the system recovery partition the other partition is where your windows is installed


try pressing the ALT key & F10 together immediately after turning the laptop on

This should invoke the recovery partition to restore windows back to how you got it from the factory


NOTE THIS WILL DESTROY ALL DATA THAT WAS PREVIOUSLY ON THE COMPUTER


so anything on it will be wiped and it will be as you got it when it was purchased

If this helped you please vote for me

P.S. Other people please note how the poster explained there problem, in great detail and not just something like my laptop wont work

Try re-installing windows by booting to cd. and if that wont work then get a new hard drive.

check the cables it properly connected or not. after start up press F8 key to check the installed hard drive is detected or not. if it is not, check with BIOS settings

Thanks Good Luck

you either have the boot priority in the bios off or you have improperly cabled your hard drive . perhaps you set it to boot to cd while installing the operating system and forgot to change the order back.
The floppy drive does not have to be present for the system to boot (if set to "not installed" in bios)
your boot devices are your cd/dvd rom and your harddrive.
Seeing as you've recently replaced the power supply , ime assuming you didnt dismantle the whole computer , just the power leads coming from the power supply, which means you only moved power , not data cables.
This would be the first thing to check -- power to the harddrive and cd rom, the 4 pin connector that sometimes connects to the motherboard and any data cables you might have bumped while changing the power cables. check these things and post here again.

sir,
Check with bios settings. also check the cable if sata activate at bios. need to check bios itself.

Usually when your BIO's doesn't detect the hard drives is usually a good indicator that the hard drive has failed. In rare instants it is the motherboard. In the boot sequence it will only show the hard drives it sees if it doesn't see any then none will be shown. I would start with a new hard drive.

Hope this helps.

Go inside to your BIOS menu then set the BOOT sequence to CD as the first boot so when your PC with the operating system installation disk inside it will load the installation wizard.
Good luck hope that helps........

There could be a number of causes. Do you hear any beeps when the computer starts up? Try seating all the chips in the motherboard. That means, apply pressure to each individual chip on the motherboard with your finger or thumb. The goal is to make sure each chip is securely attached to the board. Sometimes, heat or new h/w installs partially "pop" some of the chips out of the motherboard - causing the circuitry to be disconnected...
