Vista Disk Partitioning

[Jeff Gaines]

I am putting Vista on a test PC (I've gone back to XP on the main PC
because there are so many apps that won't run under Vista).

I deleted the current partitions from the drive I was installing to, set
up a 25GB drive in the Vista install program and let it run. I then went
to add an extended partition in the spare space on the drive and Vista
won't let me - it wants to put another primary partition on.

Are there any tools within Vista to allow me to create an extended
partition?

In the meantime I have booted to a Win98 recovery CD, ripped off the
partition Vista put on (goodness knows what it is, FDISK and Partition
Magic don't recognise it) and set the partitions the way I want them with
FDISK, but that seems an awfully long winded approach.

 

[Richard Urban]

Partition Magic 8.01 (the last version from PowewQuest) does not see a drive
that has a partition created by Vista. And, Vista will not install on a
partition created by P.M. During the install you have to delete/create and
then format using the Vista installer.

A drive/partition formatted by Vista will show up as corrupted, along with
an associated error message, when viewed by P.M.

DO NOT allow P.M. to repair. If you do, you will lose all access to the hard
drive

Vista uses a new and better NTFS type format that Partition Magic cannot
see (or do) yet.
That is why your having these issues. The NTFS format as previously known
is no longer being used and FAT32 obviously is out. Maybe a while before
the proper utilities are create that lets you tinker (or test) things out.

I ran into all the same issues a few months ago while testing Vista. Except
for me, I used a different harddrive that I just swapped in and out. That
way I don't mess up my current system.

Vista will put 3 Primary partitions on a drive and I extended. This is by
default. Doesn't matter how much space you have, if you have less than 3
partitions they will always be Primary. It is only the fourth that becomes
extended.

Is there a reason for that?
I overcame it by using FDISK but that's a pain!

We did this to simplify the process of creating partitions. Most end users
don't know or care about the different types of partitions. You can use
Diskpart to work around this--see our blog at
http://blogs.technet.com/filecab/ar...e-an-extended-partition-in-windows-vista.aspx
for details. There is also a topic in Help that discusses this.

It's a pity there's not a professional version of Vista for those of use
who do :-(

I couldn't find anything useful in help, and IE7 is refusing to save the
KB article page, I've saved this post, at least my news reader works.

If you search for "extended partitions" in Help and Support, the first topic
to appear is "What are partitions and logical drives?" This is the topic
that explains how/when extended partitions are created.

Did I miss something?
I have 2 disks in my box, each partitioned with 4 primary partitions.
During the install of both x86 and x64, Vista didn't make any partition changes.
Is this 3 primary, 1 extended partitioning only done on a blank (unpartitioned) disk during a Vista
install?

I found that, but it doesn't tell me how to create extended partitions -
just that I can't!!!

A search for 'diskpart' ends up back in the same place.

It doesn't (seem to) change existing partitions, it's when you use it to
create a partition it creates 3 x primary partitions before it will create
an extended partition. I got round it by booting to a W98 rescue CD and
using FDISK to create the partitions the way *I* want them, rather than
the way Vista wants me to have them.

Ah ha...
Interesting
I've always created partitions (unformatted) before I've installed a new OS,
and then let the new OS format the partition during the install.
I've never (at least since NT4) used extended partitions, but now that disks
are getting so big, I think it is becoming necessary (just to make a complete
backup easier).

 

[Guest]

Jeff, i can tell you how to create extended partitions using the new diskpart
in Vista but i am not sure whether you'll be able to boot off into Vista
using that partition. I think you should be able to but i am not sure. Please
post a question regarding it on
microsoft.public.windows.vista.installation_setup.

Here you go:
Boot into Vista DVD and you should be able to go to the command prompt. If
not then press Shift+F10 and you should be able to see a command prompt.

type diskpart.
DISKPART> list disk /* see which disk has enough
space on it */
DISKPART> sel disk 0
DISKPART> det disk /* just a little more fun with the
new diskpart */
DISKPART> cre part extended size=10000 /* creating a 10GB extended
partition */
DISKPART> list part /* you should see the extended
partition */
DISKPART> sel part 0 /* assuming partition 0 is the extended
partition */
DISKPART> cre part logical size=5000 /* creating a 5GB logical partition */
DISKPART> format fs=ntfs quick /* format it with NTFS */
DISKPART> assign /* assign it a volume letter */
DISKPART> list vol /* check out the new volume and its
letter */

Easy, isn't it.

Have fun with diskpart.

Thanks

OT:

Jill (MSFT):

Can you provide specific info about the changes made to the MBR (first
sector on boot disk) via Vista?

TIA

[excellent instructions snipped]

Wow Varun that's brilliant, my own instruction manual, thank you very
much

Very carefully saved, I will print and try it during my next install as
part of the learning process. I don't want to boot off an extended
partition but I never have more than one primary partition on any PC
because of the mayhem that can cause with drive letters (they may become
obsolete one day but they aren't yet!).

 

[Jill Zoeller [MSFT]]

I asked one of our developers for a list. Here's what he provided:

Functional MBR changes included:

- Trusted Computing Group (TCG) compliance [measured boot leveraged by
bitlocker].

- Default to using LBA addressing over CHS [CHS still supported].

- Obtain drive number from BIOS instead of from partition table.

- Enable the A20 gate [workaround for buggy TCG BIOSes]



Functional changes to NTFS bootcode:

- TCG compliance [measured boot leveraged by bitlocker].

- Only support LBA addressing [no CHS].

- Detect sector size instead of assuming 512 bytes.

- Load BOOTMGR instead of NTLDR. Fallback to NTLDR if BOOTMGR is not
present.

Jill:
Thanks.
This agrees with my tests, that Vista can boot from disk00 with the previous
MS MBR (DOS thru XP) provided the active partition boot code calls bootmgr
(and not ntldr).

 

[John Barnett MVP]

Existing partitions are not changed. The change comes about when you start
creating new partitions. Of course, you don't have to use Vista's disk
partitioning, you can always use a third party disk partitioning tool. This
will let you create an position an extended partition with ease.
