Can one update XP to W7 on a Toshiba laptop over writing and installing
W7? As not to loose all the old files?
I was intending to buy a new W7 disc and install from that is it
necessary to reformat and then install W7
thanks
You could try a dual boot configuration. (I'm hoping the Windows 7
doesn't absolutely insist on deleting everything in its path, and
I don't think that's the case. Start looking for recipes...)

Basically, the idea is, you resize the WinXP C: drive, to make room for
the new Windows 7 C:. So they can both co-exist on the same hard drive,
each in its own partition (files not mixed together).
Your Windows 7 DVD can do two things. If you boot it, all it presents
at first, is an "install" interface, with three lines on the screen.
Humor the DVD and click "Next". On the next page, there are some options
in the lower left corner, to do things other than install. Perhaps
one of those will be to "repair" something.
Once you get into the repair menu, the bottom option is
to open a "Command Prompt". This looks like an MSDOS box
once you get it open.
There is a tool called DiskPart, which is command line based.
You "list disks", "select disk 0", "list partitions",
"select partition 3" and so on. One of the options in there,
should be "shrink", once you've done the selecting steps and
selected a particular partition. (To do some advanced
preparation for this, you can use Disk Management in WinXP,
and look at your setup and make notes. In your case, with
only one hard drive in the laptop, I expect you won't have
a problem selecting the partition.)
What I can't tell you off hand, is whether "shrink" works for
both FAT32 and NTFS partitions or not. I've only used the
Windows 7 "shrink" on an NTFS partition. I've not tried it
on FAT32. Note that Windows 7 has a preference for NTFS, and
it won't actually install on a FAT32 partition. Windows 7
uses too many NTFS file system features, to be loaded onto
anything else.
The "shrink" function offered by Windows 7 is new, and I don't
think the diskpart in WinXP has that function. It can
shrink down a partition to half the original size, which
should be sufficient for your install. If you only had
a 60GB drive, I suppose you could make WinXP 20GB and
Windows 7 40GB or so, but that might be hard to arrange
with the diskpart shrink function, because it could only
shrink the 60GB main partition down to 30GB, and not down
to 20GB. The reason it can't shrink more, is because some
metadata on C: cannot be moved by diskpart (but third party
tools can do it). If your hard drive is 80GB or more, then
the percentage of shrink needed should not be a problem.
Once you've shrunk it, now come some additional decisions.
If you buy a Dell/HP/etc. laptop, chances are it came
with three partitions already defined. Recovery, Windows, and
Data partitions. Windows 7 will either install with one partition
or with two partitions. The reason for using two partitions,
is for versions of Windows 7 that support BitLocker encryption.
BitLocker is available with the higher end SKUs of Windows 7.
If you only had one primary partition left, you could always
install both the boot and system files in the one partition,
but then that would prevent wholesale encryption of the new
Windows 7 C:. I don't consider that a big deal, because there
are other third party encryptors if you need them.
You could consolidate your WinXP C: and the larger data partition
(squash 'em together) into one partition, but that too is an
advanced topic.
In any case, I think you could install both OSes. And because
you're installing the later OS, after the older OS has been
installed, the Windows 7 BCD based boot manager will automatically
recognize and add WinXP to the boot menu. After the install is
finished, you'll be presented with a menu with both OSes in it.
And you can then choose to boot one or the other.
If you need help, there are plenty of good recipes around to
help you. The forums over at sevenforums, are full of good
recipes. This is unlike a topic I'm working on right now,
which is just horrible in terms of information quality
(that's making multiboot USB keys).
Have fun, and before you do anything else, back up (image)
your entire laptop hard drive. You can store it on an external
USB hard drive for example.
If you have any questions about backups/cloning/imaging,
plenty of the people in this group can help with that.
You should be able to get an answer on doing backups, just
about any time of the day. What you want in a backup, is
to make sure you get the Recovery, WinXP C: and your Data,
all backed up. Some day, you're going to need that Recovery
partition, when your WinXP is attacked by a virus and you
want to reinstall WinXP, so it's imperative to back it up now.
Also, if you develop a plan along the way, to just delete the
recovery (to free up a primary partition), again, back up
everything, and you've be able to bail yourself out without
too much trouble later.
