Win 7 over Ubuntu

Hello folks,
I am trying to install win7 over a previous installation(ubuntu nn 11.04).I want the ubuntu out of there for good.I rebooted the system and saw that Win7 only "sees" 700GB and the disk is 750GB.I thought that the linux partition is still there and I want to remove it completely.I inserted a slackware cd in order to work with cfdisk and fdisk to remove the drives / partitions from ubuntu.
Of course cfdisk didnt work.Error was the usual bad primary partition partition ends in the final partial cylinder.

fdisk -l showed me two /dev/sda1 and /dev/sda2 drives.
I entered fdisk and used d /dev/sda1 and d /dev/sda2 to remove them.
I printed the table to the disk.I am not sure whether i need to remove something else as well.I removed the linux cd and the system keeps on rebooting which proves there is no OS.
After those operations I rebooted the system and inserted the Win7 cd.Still shows my drive is only 700GB.

I started cfdisk and it showed me there are no partitions on the hdd and it is indeed 750GB.I rebooted and tried Win7 setup again.Shows me 698GB of unallocated space.Then it divides it into 2 partitions automatically.It skips past "Copying win files" and goes to "Expanding Win files".
Here it stays like this and nothing happens. I did this 3-4 times and everytime if grinds to a hold on the same point.
Not sure if I should remove something else from ubuntu or what?

I also started System tools-Command Prompt from the Win7cd and tried to fix mbr.It shows its all good but my main problem remains.I tried all options on CMD.

I will try a killcd to see if that will do any good by erasing all data from hdd. My backup plan is to check the win7 cd and burn a new one.Maybe the win7 cd is not working.

Pls let me know if you have better suggestions.

if sda1 was about 50~100Mb - then that would be the w6/7 boot & system partition,
but since you say ~50Gb is missing, is that 750Gb the manufacturers disk size?.
coz - once it's formatted, then it is a little smaller - & M$ will 'see' a different disk size than a 'nix O/S would 'see' it as.

within the w7 install, be sure that it format ALL the available disk area - whatever the size it sees.

you may *not* get ALL of that 750Gb for usage under w6/7, anyway.

before you do that, however, use the 'nix live_cd to format the whole hdd to NTFS.
then boot that w7 DvD & install.
also check that the DvDs checksum is Aok & that the DvD was burnt properly.

Althought there are a lot of members here at LQ who have knowledge of windows operating systems, I would think you might be better off at a windows forum or at the microsoft site. You could just google "install windows 7 after removing Linux". I've seen howtos on that at the microsoft site. I've never installed windows 7 so I don't know the process but maybe your CD is bad?

good by erasing all data from hdd
What data? Wasn't Ubuntu the only system? You deleted all partitions?

Try the suggestions by pierre2 and if that fails, do a google search.

Thread to be deleted.This is the most ridiculous problem I have ever come across.Turns out if you burn a win7 cd on x2 it reads fine from it.If you burn it x8 or x4 Windows fails to read and freezes @ "Expanding Win files".I was doing everything right.I didnt take into account the stupidity of MS systems.
Disk size is normal.Thanks for the info anyway.

Not ridiculous at all. Linux, qnx, bsd's all have issues when burning a disk.
