[SOLVED] How to fix "GPT Partition Table is invalid"?
location: linuxquestions.com - date: August 7, 2012
Suddenly, I found out that; my GPT Partition Table is invalid.
I don't exactly know why it happened at this time.
I can boot into first 4 partitions, but not the ones after that (5,6,7)
Cannot copy GPT partition data on Linux Mint 12 KDE to Kubuntu formatted MBR
location: linuxquestions.com - date: June 19, 2012
I have a Linux Mint 12 KDE drive which has a GPT partition.
I also have a newly constructed Kubuntu drive using MBR partitions.
I simply want to copy the data from the Mint 12 KDE drive to partitions on the Kubuntu drive.
The partitions involved in both cases are:
The partitioning is the same on both drives in that / and /home are the same sizes (approximately).
I can use either Mint 12 KDE or Kubuntu on the same machine but not both drives at the same time
because of GPT and MBR partition problems.
I have tried various methods to copy the /home and /big partitions from the tower to a Kubuntu drive in a USB enclosure
but the files won't copy over with cp or rsync.
The / partition is already established by loading the Kubuntu system so I don't need to do anything except load a few programs that exist on the Mint 12 KDE drive to the Kubuntu drive via apt-get.
I actually have a working Kubuntu system which only needs the customizations and files on the MInt
Hibernate doesn't work on GPT partition
location: ubuntuforums.com - date: May 14, 2011
I was finally able to triple boot Ubuntu, Windows 7 and OS X on my laptop. In order to do that, I had to use a GUID partitioning table (GPT) to get OS X installed but Windows requires a MBR partitioning table.
To get it all working, I formatted my hard drive to GPT, installed OS X followed by Windows then Ubuntu. Then booted to Ubuntu and installed a package called gptsync which, from what I understand, simulates an MBR partition for Windows to work. Which means it has to also simulate four partitions even if I have more. Creating more (and then running gptsync to get Windows to work) would be useless because none of the operating systems recognize it. I'm also unable to create logical partitions in GPT, only primary.
When installing Ubuntu, I wasn't able to setup a partition for my swap drive. I did this after all installations were complete. Added the drive to fstab and after a reboot (ran gptsync as well before that) the hibernate option appeared on the power but

swapon -s return no swap partition for my Ubuntu system.
Filename Type Size Used Priority
I do have a swap partition, but from what I understand, the Slackware install I intended to use with the same swap partition have probably changed the UUID or something. This is my blkid entry for the swap partition:
/dev/sda8: UUID="bac99b00-3241-4faf-94d9-197c94cfd94d" TYPE="swap"
I can right click the swap partition in Gparted and select swapon, which will then cause swapon -s to show it like this:
Filename Type Size Used Priority
/dev/sda8 partition 4227068 0 -1
It is gone after a reboot though. swapon -a, no matter if I have enabled swapon in Gparted or not, always gives this feedback:
swapon: cannot find the device for UUID=c6cd4dc1-cfa5-46f2-9bf7-4dd91fc1baeb
swapon -s displays sda8 as swap partition immediately after startup in Slackware, with no further action required.
Windows installation error GPT partition
- date: April 28, 2013
I am using Ubuntu-12.04 - 64 bit on my Lenovo G580 i5 laptop.
I have googled how to install window 7 after installing ubuntu and found out couple of good posts.
I have re-sized my partition table and made space for window 7 (Screenshot attached).
But when I try to install window7 (both 64 bit and 32 bit) it gives an error that:
Windows cannot be installed on this disk. The selected disk is of the GPT partition style
I have searched and found out about UEFI and GTP stuff (which is beyond my understanding), and found out that either I have to use Gparted and create new Partition table or have to format my hard drive.
I don't want to mess up my ubuntu installation, because I have very important data and settings on it.

installing linux on extra partition
location: linux.com - date: October 8, 2010
hey i was wanting to install Ubuntu on a 90 gig partition I made in windows that will allow me to Dual-boot both. I've used the Wubi installer to do it before but this time i was wanting to do it myself since wubi only allowed a max of i think 40 some gb's. So since i have 90 gigs of unallocated space i was wandering if i need to do something with the filing system or while installing Ubuntu it will recognize the partition and be able to use what filing system it wanted to?
Any help is appreciated.
Resizing a GPT partition with a ext4 filesystem
location: ubuntuforums.com - date: January 24, 2010
I'm trying to resize (grow) a large (3TB) GPT partition with the ext4 filesystem on Ubuntu Server 9.10 amd64.
I'm having some problems figuring out which tools to use, and the sheer amount of information returned by googling has left me a bit confused. So far I have boiled it down to the following:
I can't use fdisk to resize the partition because fdisk doesn't support partitions larger than 2TB I can't use gparted because:
1) It's a headless server and I don't have physical access to it right now.
2) The developers of gparted have issued a warning regarding ext4 filesystems: http://gparted-forum.surf4.info/viewtopic.php?id=13960 My best bet seems to be the parted resize command and resize2fs, if I have understood the manual for parted correctly
The man page for parted says:
ext3 filesystem functionality does not currently work. To manage ext3 type filesystems use tools like resize2fs(8 ) or mke2fs(8 ). Note that the currently

I was hoping someone might take a look at a problem I'm having with an old drive I re-purposed to shuffle some data around on. Sadly it won't mount as it did before and disk utility (Palimpsest) is saying there is just free space, no partition. I've been reading up on this stuff myself, but, I think I'm missing something, or I'm out of luck.
Not sure how this has happened, drive was formatted with a guid table and a single ext4 partition created on it, all within disk utility (Palimpsest). I moved the data over to it, powered down, moved drive to new machine, booted, partition gone, returned to first machine, still missing.
Note this isn't the boot disk.
The following sums up my attempts so far (not including my fruitless foray with testdisk)
gdisk (gpt fdisk) and fdisk with the following results:
:~$ sudo gdisk -l /dev/sda
