Unable to Partition further!!!

[rctektip]

I have a new thinkpad t42p.
It has a 60GB hard drive on it. I tried following partition:<br>
C: -- NTFS --PRIMARY --7GB Windows XP Home
/boot ext3 --PRIMARY -- 100 mb LINUX BOOT
SWAP --LOGICAL -- 1GB LINUX SWAP
/ ext3 --LOGICAL -- 19GB LINUX /
Now i am left with 30.17 GB unallocated.
I used windows ControlPanel->Computer Management->Disk Management - > New partition and created a 10GB Partition out of the free 30 GB.
But suddenly the remaining 20 GB becomes unusable!!!
when I right click on it, it shows "New Partition.." Option faded(inactive)!!! How to get around this? Please help.

rctektip,

The MBR only holds descriptors for 4 partitions. You are limited to creating four primary partitions per disk, or three primary partitions and one extended partition with unlimited logical drives.

Your extended partition must be allocated a specific size or space. You must/can then create any additional partitions within your extended partition up to the size limit allocated to it.

The above is using a MS partitioning tool. 3rd party tools somrtime workaround these coventions.

This link is a history and a bit deep but contains good info.

Hope This Helps - - If not Please post back with some information as to what application(s) you used to establish the current partitions.
