I have lost the facility to press f2 or f12 on boot!

Well I haven't found the Utilities folder, but I have found the HW Setup file, run it and selected Default, and got the slow BIOS back!
I then ran my recovery disc and did a factory reset of Windows, BUT the Ubuntu loader screen still appears on boot up. Please, is there any way of deleting the Ubuntu, as I would like my machine to be exactly as it left the factory - just Windows 7?
It's very kind of everyone to help me as above - I just have this last thing to sort now, and hope there may be an answer to that!
Many thanks,
Stuart.

Glad to hear you found the HW Setup file and can use slow BIOS again.
You should add the Toshiba Laptop Model# (C660) to your SF specs.
Then folks here trying to help you could look up specific instructions for your laptop.

You should post a disk management screen shot of your PC:

Dual booting with Linux (Ubuntu) has it's own set of issues from what I know.
I think you are using the Linux GRUB booter now ...

Here is a tutorial for removing an OS from a dual boot PC.
It's for 2 Windows OSs, so Ubuntu may have some special differences.
It should give you an idea of what's involved, and you can post questions in that tutorial if you want to.
Dual Boot - Delete a OS

I think you need an installation expert now, and maybe this thread should be moved to the "Installation & Setup" SF forum.
I'll ask others for help about that ...

Hi. I went to this site which I found by Googling - How to Erase Ubuntu: 10 Steps (with Pictures) - wikiHow , and managed to get the machine to now boot up in Windows, which is what I wanted!
Many thanks, David, and all the others above, for help with this.
Stuart.

You're welcome and glad to hear you fixed it.
Thanks for posting the solution.

Wipe the HD with Diskpart Clean Command

Then do a the vastly superior Clean Reinstall - Factory OEM Windows 7.

No tech enthusiast would run the bloated factory preinstall larded with crapware and useless duplicate utilities which interfere with better versions already built into Win7.

I couldn't access boot menu on a Toshiba Satellite p50t-B to install windows. I tried EVERYTHING f2 and f12 didn't work. Eventually I found out it was stuck on Hibernate mode and the hard wired battery was keeping it in that state. I had to press a tiny button on mother board next to memory, that fixed it. Unplugging battery might as well.

The cure all would be to clear CMOS. Unplug the computer. Press and hold the power button for 30 seconds. Remove the CMOS battery. Or simply use the reset CMOS button on the motherboard.

BTW- Old thread.
