Now I can squeeze SDA2 down in Vista to half,
leaving unallocated space.
But this space can't be formatted for Suse Linux
as it says that I can only have 4 Primaries.
And here I thought that I could create a logical
extension for Linux.
I need to go to Windows once in a while, and some
of the features of this laptop might only be on the
windows side.
So, ... do I kill one partition, such as the HDD Recovery,
SDA4, but somehow leave the space empty, thus "freeing" a
Primary partition? I've done the initial laptop Create Recovery Disks thing which took 2 DVDs (about 6 Gb) which should replace
it when needed.
I gather that Vista is always making up a series of CD
zized images of itself for recovery from a certain state.
So / root, /home, /Swap will take up more partitions, though
once I have cut, squeezed, chopped the 133Gb in half for this Linux install (i'll be adding eCs, the modern OS/2 sucessor later), they should take or will they need an
apparent Primary partition also.
The recovery disks seem to be Norton Ghost images to restore the HDD parition and the complete image of the
remaining Windows Gigabytes of basic stuff in Vista Home.
Maybe there is a better way to restore the Windows part
by DVD/CD that would obviate the need for these three
extra-partions.
Yes, if you need to boot windows, your partition table must be Microsoft compatible, and that will give you max 4 primary partitions.
Add an external USB disk , a 500GB don't cost much today.
Download the rescue CD .
http://partimage.org/Main_Page , follow the link to System RescueCd Homepage.
Boot it and format your external USB disk ( fdisk /dev/sdb )
create one linux partition sdb1. Make a filesystem mkfs.ext3 /dev/sdb1
(not vfat)
Then mkdir /mnt/backup : mount /dev/sdb1 /mnt/backup
then run partimage
Do backup of all your partitions
When you have a backup of your partitions, save the output
from fdisk -l /dev/sda , and halt the machine, and remove your usb disk.
Boot windows , and defrag, reduce D: , leaving enough with free space.
Boot the rescue CD again
and, mkdir /mnt/backup , and mount your usb disk again , and cd to it.
do ls -l to verify you have your backups, so you didn't do any mistake.
use fdisk /dev/sda
remove sda4 , sda3
make a new extended partition 3
then create 2 partitions, with the same numbers of blocks as the saved output
(answer +numberofblocks) from fdisk -l
Use T to toggle type 7
Make one partition 1G I guess ( answer +1G as endblock),
and change to type 82 (swap)
And then make another one with all remaining blocks and
set type 83
use p to see the table
w to save it
now your swap should be sda6 and the linux partition sda7
Try mkswap /dev/sda6
(that will help when you start the install.)
Do ls -l , write down the names of your backups.
..000 is added to the name you gave.
Start partimage, and restore your old sda3 to the new sda4 ,
but DO NOT restore the old partition table and MBR.
If you like, you can also restore the recovery old sda4 to the new sda5 ,
but booting in recovery will make it all undone, so you can keep it as
an image and restore if you need it later.
If you boot now, windows should see it's partitions as before, but smaller sda2.
Now suse should find the swap sda6, and use it during the install, and suggest using sda7 as / , if not, tell it.
You don't need a /home on that small disk, and remember, the disk is almost
100% faster on the first cylinder (where windows are) then the last where Linux are.
You should get another disk if possible.
And, btw. everything I write can be outdated, if suse's rescue boot has better tools, things are changing fast, and sometimes I do the old obsoleted way :-)
