Boot Drive Size

[John]

I just ran the Vista upgrade advisor, and it says I need a bigger drive.

My 74GB Raptor is partitioned into C:\ 30GB and D:\ 40GB. Windows XP is
only using 16 GB, and I have no data on C:\
I have some data on D:\, but am considering using it to possibly dual boot
Vista.

I have two 500 GB drives for the big stuff.

Shouldn't either of these partitions be large enough for Vista if there is
no data on them? Or should I merge the partitions into 70 GB for Vista?

Hi,

30GB is plenty, I suspect something else is being looked at. Possibly the XP
partition, or something carved out by a third party boot manager. What is
the active partition?

30 gb is heaps. I got 25gb partition that i have vista installed on. Vista
takes up about 10 or so gigs straight after install

The C:\ partition is the active one.
Perhaps the upgrade advisor is only looking at that partition, and thinks I
only have 30 GB total drive space?

Hi,

Well, if XP is using 16GB, it's possible that setup sees insufficient space
available. A Vista install likes lots of drive space.

If it is calculating based on an upgrade and not a clean installation then
the windows.old file would consume too much space.

 

[Marcus Wulf]

The Upgrade advisor is just looking at how much free disk space there is
left on the drives.

I did this too and it tells me that because there are 20 GB out of the 30 I
have on drive C: are used there is not enough space left for Vista.

If you do a clean install 30 GB for Vista are enough.

Try resizing the partition larger, installing Vista and after that is done,
downsizing it again. Should work.

I installed onto a 40gb partition.. then I installed Office 2007.. I now
have 50% of the partition free which is not so much really... to maintain
good primary drive performance, one should look to keep 25% free, so I do
not have that much space left to install other things..

I have installed Vista on a drive with a partition of 25GB and have also
installed a lot of additional software and add-ins and still have 20% free.
I cannot see a problem (I am running Vista Ultimate RC1 which I understand
has additional debugging code which I believe will take up more space so if
you are installing the RTM version...! I will happily hold my hands up if I
am wrong!!)

I've installed Vista onto 17 GB clean partition without any problem. You
must have AFAIR a minimum 15 GB free space on hdd.
