Install of WindowsXP: does it delete MDV partitions?

August 04th, 2010 - 08:33 am ET by VMunich | Report spam
Hi everyone,

yes I know, my question is not 100% related to Mandriva, still the
question may be relevant for many of us.

On my laptop I installed (years ago) Mandriva and windowsXP (Windows
on the first partition sda1 of my HD).

I need to reinstall Windows and I seem to remember that the install
process of WinXP does ignore the other partitions present on the HD...
means that my Mandriva partitions would be deleted during the
install...

Has anybody a clue ?

Thanks !
Vincent

That was always my belief, but it doesn't seem to happen with XP. On a
first install on a fresh drive, I always install Windows first. But I have
repeatedly reinstalled Windows XP from scratch, and GRUB has been unaffected
every time. That can be a disadvantage. By design, you don't boot from the
XP CD unless you press a key. As a result, when the Windows installer
reboots the system during the process, I have to be on hand to choose
Windows from the GRUB menu. The last couple of times, I have used the
Mandriva DVD to put the Windows bootloader back at the beginning, to make
things happen as intended. Even the gurus are resigned to reinstalling
Windows about every 6 months. Because Windows is my second OS, mine lasts
longer. In a lot of ways XP is ideal for the dual-booter.

Does this perhaps happen only with reinstalls?

In answer to the original question, XP won't take over your whole drive.
It prints a list of partitions and asks you to choose. Other versions
of Windows may be different, as you say.

Doug.

This is very exceptional indeed. But then again, there are many factors
at play here, such as...

- Is this an OEM version of Windows or a machine-independent
license? (Presumably the latter.)

- What version of Windows XP is this, i.e. Home Edition,
Professional Edition, and what have you?

- What Service Pack release of Windows XP is this?

All of the above play a role in how nicely or how badly Windows plays
ball with any other operating systems installed on the same computer.

That can be a disadvantage. By design, you don't boot from the
XP CD unless you press a key. As a result, when the Windows installer
reboots the system during the process, I have to be on hand to choose
Windows from the GRUB menu.



That's because of two other things, i.e.:

- The fact that Windows requires reboots during installation;

- The fact that Windows was never designed to be used on the
same machine as other operating systems, which is a corrolary
of the above.

The last couple of times, I have used the Mandriva DVD to put the
Windows bootloader back at the beginning, to make things happen as
intended. Even the gurus are resigned to reinstalling
Windows about every 6 months.



Which is of course a flaw in the design of Windows.

In which case I think the most important difference is between an OEM
version of Windows intended to be used on the machine it came with, and
a separately bought enduser version.

The OEMs don't play nicely and tend to claim your entire hard disk, and
especially so if they come on a so-called recovery CD. Such machines
don't have an actual "installable" Windows CD, but instead come with a
manufacturer-supplied CD that also contains the manufacturer-supplied
application software, additional drivers, et al.

And in some cases, these recovery CDs aren't even recovery CDs, but are
instead installed in a hidden partition - typically at the end of the
hard disk. I believe that this was the case with my brother's old
Compaq Presario.

That is how my Compaq Presario is set up.
Vista is a disk space hog as well taking up
far more space than the size of the OS. I used its
built in disk partitioner to carve off about 75 GB
for my Mandriva install.
