GParted in UBUNTU shows entire disk as UNALLOCATED SPACE

[Shadius]

It usually is not gparted, but Windows (or third party Windows partition tools) and sometimes testdisk that cannot count and make extended too large.

Hey oldfred

I believe it was you who helped me with my issue of GParted showing my entire disk as unallocated space.

So I wasn't right about sda4 being larger than the disk drive itself?

[Prescilla]

Okay, it seems the problem is sda4 instead. Notice that it ends at 625153409, but the total sectors of the disk drive are 625142488. So if you do that math, it's over by 10921. You will have to shrink the size of the partition to bring it back into the disk drive, so to speak. Sorry for the confusion, but I'm sure that this is the problem, this time. You might wait for a second opinion on this also.

Yes, I think you are right, so the question now is how do I modify the extended partition (sda4) to match the end the total sectors???

Here's the output of the parts.txt

# partition table of /dev/sda

I already copied that file to a USB disk.
What to do next? Is it safe to use fixparts?

I tried fixparts /dev/sda and type p, here's the output:

FixParts 0.8.4

MBR command (? for help): p

The extended partition was not listed, but will it be fixed???

That part I'm a little unsure about, but I've used GParted to resize my partitions before. I imagine it would be the same.

That's where my problem lies. I have been using GParted for partitioning and since it shows my drive as unallocated space, I can't do anything.

Do you know how to use fdisk? I guess I'll have to do some research first.
Thank you again.

Unfortunately, I'm not familiar with fdisk as I am with GParted. You might want to take a look at FixParts. If you ever solve this, please post back here and let me know what you did to solve it, if you can.

Hello again. I have tried fixparts and it did solve the unallocated space issue.

But then again I still can't boot into Ubuntu. I still get the

error: hd0 out of disk. Press any key to continue...

You get that error when trying to boot into Ubuntu? Have you tried using the GParted LiveCD now to see if the partitions show up properly after using FixParts?

[oldfred]

Unless you ran the command to write after starting fixparts it does not correct the error. Did you press w?

Yes, I did use the w option to write the partition table to disk. And I knew that it was successful since I can see all my partitions in gparted.

The only problem now is the

error: hd0 out of disk. Press any key to continue...
