BIOS not working in DELL INSPIRON.

Hello everyone. I have DELL INSPIRON N5010. I was using windows 7 home basic 32 bit os. I wanted to change it to windows 7 ultimate. So I have inserted windows 7 Installation disk into CD drive. Then I went to through the installation and I chose the Custom as the installation type.When the partition page appeared, I have formatted all the disks including C which contains windows files. Then I got 298 GB unallocated space. Then I split them in to 4 partitions. Then I have selected one partition to install the windows. Then installation started .
Copying windows files succeeded.
Expanding Windows files(0%) is still be like that for 20 minutes. Then I got the error message like,
windows cannot install required files. error code 0x80070017
And I thought it would be the installation disk problem. But it works fine in other systems.
I tried several disks. No use. Also I got another problem.
when system boots I tried to enter into BIOS using F2 and F12 which was mentioned in screen. But it did not enter into the BIOS, Instead it goes to the installation.
I do not know what to do. Help me to get rid of this.

Thanks in advance.:)

I would suggest using a different DVD drive, or maybe copying the installation files to a USB stick (4gb or bigger) and performing a USB install.
The error 0x80070017 translates to "CRC Error" which means that the files that are being copied from the disk are not making it to the hard drive with the same structure, meaning that the "original" files on the disk are being modified/changed/corrupted while being copied to the "destination" location on your hard drive during the install.
This usually means either a bad DVD, or a read error on the DVD drive.
The easiest thing is to make a USB drive to install Window s7 (and it's WAY faster than DVD too!)

I hope this helps.

What size is the partition that you are trying to install windows on?
I would recommand no less the a 60Gig partition to install windows on, this allows you 45Gigs for the OS and some room for updates and some programs which really like to install files into the Windows folders.

Why did you partition the drive into 4 partitions?

You have deleted the Dell Utility Partition & Dell Restore Partition. F2 & F12 are no longer functional. They use a non-standard MBR which is probably why you are getting CRC errors. Reinstall Home Basic from the Dell discs. Then install Ultimate over Home Basic.

Thanks for your suggestion.
First I was using Windows 7 home basic 32 bit . But I have been trying to install 64 bit OS. Might be that is the problem. So, first I installed home basic 32 bit OS. Then I upgraded it to 64 bit . I am not sure about the solution . but it worked for me.

But the functional keys still not working.
