View Full Version : [ubuntu] Missing Partitions in Installer (8.04) on HPNX9420

Hello,

I try to install the Ubuntu 8.04 LTS on my Notebook (HP NX9420).

Unluckily, when the Installer starts and Step4 (Partitioning) occurs, it doesn't display my Partitions. I just have the option to use the whole HDD (which i won't try ;)).

When i switch to the Console with ALT-F2 and use "sudo fdisk /dev/sda" followed by "p" - it does show me my Partitions.

Any Ideas?

If you have Vista; use Vista partitioner. If you have XP; use Gparted Live CD and 'shrink' XP.

First, the primary OS is XP, not Vista.

That's not the problem anyways - I already have the System partitioned from a previous Linux install. BUT - if the (existing) Partitions don't appear in the Partitioner of the installer, i cannot chose them as Rootfilesystem, eh?

Do you have the option to go 'Manual'?

Yes, I can go "manual" - but then it doesn't respect my current partitioning and presents my HDD as it would hold no partitions at all. (there are 4: WINDOWS, RECOVERY, Linux / and Linux Swap).

But I need to preserve my Windows system and just delete the existing Linux/Swap Partition and re-use it for hardy.

It could be a bad burn. Burn a new CD. Do md5sum, burn at 4x or less, check CD integrity after burn. Use CD-R. Clean the lens in your burner. Try your CD's in diferent computers.

Checking that.

MD5 was corrent. Now burning with 10x (the lowest speed my writer does ;I)

thanks, so far.

//Update:

Checked CD, re-burned, remade ISO to check MD5: OK

Still the same effect - when i choose "manual", it just shows me /dev/sda in the listing as if there was no partition at all.

One thing that makes me a bit susicious when i view the Partition with fdisk:



bma@fsisp:~> more fdisk.txt

Partition table entries are not in disk order


Can this cause an exception in the Graphical Partitioner? cfdisk won't work either.

You could have a Partition Table problem. Check with TestDisk:

We're arm wrestling with a very similar problem in this thread here:

I have the exact same problem. When the partitioner loads, it just brings up my hard disk (/dev/sda) with just the Create Partition button highlighted. It seems to think there are no partitions on it. I obviously don't want to wipe out the whole drive. Any resolution yet?

It seems there is some issue in the partition table:

Testdisk reports
Space conflict between the following two partitions
4 E extended LBA 15507 0 62 24321 41 40 141599472
1 P FAT32 LBA 23994 238 53 24321 41 40 5240832 [MEDIADIRECT]

How does one resolve this?

I think I have the following partitions:

Dell Utitility
Dell Mediadirect
Vista (two logical partitions)
Ubuntu

Thanks!

If you are running XP, get Gparted Live CD: http://gparted.sourceforge.net/download.php
Burn to disk and boot from it.

I already have the System partitioned from a previous Linux install.
Just wondering if the previous Linux was PCLinuxOS or Mandrivia. Or if you have used the DiskDrake partitioner? fdisk shows sda1 and sda3 overlap at 9656.


/dev/sda1 * 1 9656 77558008+ 7 HPFS/NTFS
/dev/sda3 9656 11071 11374020 83 Linux


This is an invalid partition table and GParted and the Ubuntu installer partitioner sees that and says unt ua I ain't doing anything. Might try to fix it with DiskDrake.
