[ubuntu] Cannot change partition table?

view story
linux-howto

http://ubuntuforums.org – Hi, I recently decided to put ubuntu on my eee 1000 rather than windows 7. The problem I'm facing is that whatever changes I make to the partition table (be it via fdisk, sfdisk, gparted, ubuntu installer) are lost as soon as I exit the application, reverting to the old partition table. nothing seems to stick. None of the applications report any errors in what they are doing, but next time you load them you are right back where you started. I've even tried using parted magic to the same effect. Help! (Hardware)

Stories similar to [ubuntu] Cannot change partition table?

Suppose I have some drive with a single partition. For some reason I decide to repartition it, using fdisk. I create multiple partitions, then write the partition table, then exit fdisk.

Hi I had an 70GB ubuntu partition and I installed windows 7 on the rest odf the disk. After the installation the ubuntu partition seemed deleted, I used a live cd and gparted showed that parttion as unallocated space. I found here an old thread saying about TestDisk and how I could copy my lost data. I followed the instruction, installed TestDisk and found my lost ubuntu partition.

I have an issue, not necessarily a problem. I have a disk, which had Ubuntu 11.04, a swap, a big NTFS and some free space. When 11.10 came out, I did a fresh install and recently I've deleted the 11.04 partition since I didn't needed it anymore. I've noticed that my partition table is a little bit messy.

I have windows 7 and wanted top replace them with 12.04 but when I was booting and starting installation of ubuntu I chose replace windows in my ssd and it saw this problem. "/dev/sda contains GPT signatures, indicating that it has a GPT table. However,it does not have a valid fake msdos partition table, as it should.

I working on Ubuntu 11.10 I have used Gparted for formating my pendrive (2 GB) but unfortunately I have lost partition table for the same . And I unable create it using same SW Gparted . So plz help me out and tell other to create partition table

Thanx in Advance .

hi,

i'm trying to make my imac capable of triple boot.

the software i use are:

mac os x 10.5.8 win vista sp1 linux opensuse 11.2 and, rEFIt GParted

i used the diskutility to create 6 partitions.

1st. is for the EFI 2nd. is for mac 3rd. is for linux 4th. is for windows

I first noticed an issue when trying to install Linux Mint 14 as a third OS alongside Ubuntu 12.10 and Windows 7 - I was unable to create another partition to install Mint to.

Poking around, I realised that I had reached the limit of primary partitions: (from left to right of the table) 1) a ~100 MB primary partition that I meant to use for storing Grub files but never got down to, 2) a 25 GB ext

First I create a properly aligned partition in a new GPT table using parted by specifying percentages for start and end of the partition:

# parted -a optimal /dev/sdb GNU Parted 2.3 Using /dev/sdb Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) mktable gpt Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost.

I ran fdisk on the wrong HD. I basically cleared partition table, pressed w and quited fdisk and only then realized that that was my main harddrive...

I got this message:

WARNING: Re-reading the partition table failed with error 16: Device or resource busy. The kernel still uses the old table.
