Can I safely remove Ubuntu???

Hello,

I am having Fedora 11 installed on my laptop. I installed Ubuntu 9.04 a few days back but I don't seem to like it. I had installed grub loader of Ubuntu 9.04.

Code:

fdisk -l

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xa5a2ee93

   Device Boot      Start         End      Blocks   Id  System

/dev/sda6           11260       18698    59749375+  8e  Linux LVM

Disk /dev/dm-0: 57.0 GB, 57088671744 bytes
255 heads, 63 sectors/track, 6940 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

Disk /dev/dm-0 doesn't contain a valid partition table

Disk /dev/dm-1: 4093 MB, 4093640704 bytes
255 heads, 63 sectors/track, 497 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

Disk /dev/dm-1 doesn't contain a valid partition table

Is it safe to remove Ubuntu that's installed on /dev/sda1. /dev/sda5 is the /boot partition of Fedora 11. Deleting /dev/sda1 using gparted is ok? And will it boot Fedora's grub loader after I delete that partition?

Why ubuntu root partition (/dev/sda1) is ntfs ?

shahdharmit · #5 23rd September 2009, 03:40 PM

Actually after running blkid -L I am wondering about the same thing. I formatted that part of my hard-drive. OS was the label that I had kept when I had Vista on /dev/sda1 about 3-4 months back. But then I installed Windows 7 for time-pass and finally Ubuntu a9.04 a week back. I expected it to be ext3 as well.
File Systems tab in Applicaitions->System Tools->System Monitor shows me it as ext3 only.

Edit only this part of grub.conf so:

Quote:

title Ubuntu 9.04
root (hd0,4)
kernel /vmlinuz-2.6.28-11-generic
initrd /boot/initrd.img-2.6.28-11-generic

save grub.conf and close.

Try to boot ubuntu (if possible) and insure which is ubuntu root partition.

shahdharmit · #7 23rd September 2009, 04:08 PM

Sagitter, I don't think there's any meaning in doing so because Fedora boot loader doesn't load. It's the Ubuntu boot loader that loads when I boot my machine. If it had been Fedora boot loader, then I would've simply deleted the /dev/sda1 partition using gparted and then removed the entry from grub.conf.

Sagitter · #8 23rd September 2009, 04:20 PM

My advice on post #6 serve the purpose to check partition contain.

Sorry.. I didn't get you. I can run Ubuntu perfectly well. I wish to delete Ubuntu. Sorry Sagitter, I didn't understand what you meant to say.

Sagitter · #10 23rd September 2009, 04:32 PM

No problem shahdharmit

/dev/sda1 is a ubuntu partition?

shahdharmit · #11 23rd September 2009, 04:40 PM

Thanks for clarifying Sagitter.

Yeah /dev/sda1 is the root partition for Ubuntu. During the installation of Ubuntu I had set it as / partition for Ubuntu. So it means that it's the root partition for Ubuntu, if I am not mistaken.

stoat · #12 23rd September 2009, 07:35 PM

Hello shahdharmit,

Consider this idea. Before you do anything to Ubuntu, boot into Fedora, open a terminal, and re-install Fedora's GRUB in the master boot record with grub-install /dev/sda. When you then reboot, Fedora's GRUB should boot directly from BIOS, and you can then reformat /dev/sda1 for other uses. That should accomplish what you want with minimal disruption to Fedora's booting.

shahdharmit · #13 24th September 2009, 04:13 AM

stoat, before reading your post, I had already done all those things that you had kept in do-not-do section. I removed Ubuntu from my machine knowing that I'll get an error. Finally I installed Fedora 11 on /dev/sda1 which made 2 partitions having Fedora 11. Then I checked your post and from the fully updated Fedora, I did grub-install /dev/sda which made things okay, finally. Thanks. I know I messed up my laptop like a fool.
