[SOLVED] can't detect partition

**phillycheese113** · 12-31-2010

i'm dual booting with windows xp and during linux mint 10 installation where it ask which partition to install on, it. it didn't list any windows partition it just list the whole unallocated partition. same thing happen with gparted live cd ---- so something wrong with partition table.

using bootinfo script i get this text file.

Code:

sdb sdc sdd

so what do i do?

**Lostfarmer** · 12-31-2010

so something wrong with partition table

/dev/sda3 overlaps with /dev/sda4

It would seem that you tried to change the partition table at some point, what program did you use , what did you do ?

Does XP boot OK ? Is sda4 only storage or do you have any XP programs installed to it ? Does XP give any errors when you access sda4 (likely drive D

?

Boot sector info: According to the info in the boot sector, sda4 starts
at sector 63. But according to the info from fdisk,
sda4 starts at sector 148633443.

That information indicates that sda4 was a logical volume but now it is a primary partition.

sorry for the late response, just got back from new years celebration.

anyway recently I had delete linux root,swap,and home partition using windows diskmanagement and here I am.

Xp looks okay and running well. sda4 is drive D for storage of videos and music files. There is no errors when I access drive D from windows, and no xp programs are in drive D.

What I would do is use a live linux and run 'fdisk /dev/sda' .
m=dislpay menu
p=display partition table

step #1. press 'd' for delete partition
#2 enter '3' for the extended partition entrie
#3 press 'p' and make sure it list sda1, sda2 and sda4
if all looks good press 'w'- write new partition table to disk.
if it does not look good press 'q' to quit with out written new partition table.

What you will end up with is sda1,sda2, unalloted space,sda4.

Do not know why XP's diskmanagemet messed it up.

You may be adviced to wait and see if any one else see's a problem with my method.
