I just upgraded from Lion to Mavericks. Now my Bootcamp partition has been shrunk to 8,51 gb, down from 150+gb and it is no logner bootable.
Here is a picture of the partition layout:
disk0s3 is a Ubuntu partition, which has also been resized. I'm pretty sure the 'empty' space under BOOTCAMP is in fact all my Windows data. Any help is greatly appreciated! 🙂
MacBook Pro, Mac OS X (10.6.7), i7
Since originally installing Windows in Bootcamp have you re-sized any partitions?
As you have Ubuntu installed I suspect you have.
This is not supported for Bootcamped systems and although it will keep booting, when you run an upgrade installer it will try to correct it - and fail.
It may be that your system's mbr has been renewed and the start/end blocks of the Bootcamp partition have been lost.
It may be recoverable but it can be a long job. If Testdisk can find the old Bootcamp's start and end blocks you can make a note of those and re-create the partition (or at least possibly recover files).
If that works you would then need to create a new hybrid mbr with something like gdisk.
It's a long and risky road with no guarantee of success.
It might be easier to wipe the drive and start again if you have everything backed up.

The Mavericks installer didn't 'want' to install Mavericks on my system. I read in Apple's support pages, that this is a bug, and it could be fixed by making the Mac partition slightly smaller. I did that. Installed Mavericks, and now Bootcamp is broken.
Assuming you used Disk Utility to resize the "Mac partition", that action is not supported if you have a Boot Camp partition. You will have to erase and format your hard drive then reinstall OSx and start again with creating a Boot Camp partition.
There ought to be some way to resolve this, other than erasing everything.
TTBOMK there is not
Is there any way that I can atleast retrieve my files?
Assuming that you don't have backups, then you will need to check out recovery software for Windows and Ubuntu for that.
You should be able to recover something but I seriously doubt that the software will find everything for you.

There are several posts by a member called murphychris on this very issue. There are currently a couple of threads on other forums. Here's one such thread and there are others

This would be a good place to start
Mavericks altered BootCamp partition.
