Ubuntu recognize hard drive with windows on installation

Asked by Seth Barker

Hi, I am trying to Install Ubuntu 10.04 lts on 300 gb hard drive with windows 7 on it. I know my Win 7 is in the ntfs format and only using 150 gb of the 300 hundred and I formated the rest of the hard drive using a linux live cd in ext 4. I start the Install and when i get to the part where i need to choose the partition to put linux on it doesnt recognize the hard drive. Can anyone tell me why? I am using a maxtor hard drive could that be why?

Can you boot your pc entirely from the Ubuntu live cd and select try Ubuntu

Then open a terminal from Applications→Accessories→Terminal and please copy and paste here the result of the

sudo fdisk -l

command.

Thank you

NTFS appears split into two partitions without proper separation which may have been caused by a mistake somewhere in the ext4 formatting process. My guess is that the ext4 partitioning didn't complete properly. Hopefully there's no damage to your Windows 7.

What I'd do (your choice of course) is to boot into Ubuntu 10.04 as a Live CD only and start Gparted from System > Gparted. Once that screen comes up, select and delete the ext4 partition which will create a block of unused space. When completed, go to the pull-down menu Gparted and select Refresh Devices to verify how things have gone. Then close Gparted.

At this point you can probably click on the "Install Ubuntu 10.04 LTS" link on the desktop. Let the installer do the partitioning of the unused space to ext4. At this point keep your fingers crossed.

If Ubuntu 10.04 LTS does install, remember to get all the "official" updates which now include even a kernel update.

Can you help with this problem?
