Partition question

[SusiL]

I'm currently trying to add OpenSUSE to my Laptop which already has Vista Ultimate installed, hoping I will end up with a dual boot system.

Currently, my HD is divided into four partition: Vista Ultimate with Bitlocker enabled needs two partitions - one for the unencrypted boot files, and one for the rest of the system. Then I have an unencrypted partition for data that I don't want encrypted, and finally the partition in which I plan to install Linux.

I have already installed OpenSUSE to that fourth partition, and it worked just fine. But now, I'd like to reinstall with LVM, so that I can use encryption as well. Upon installation, however, I get the following error:

Error
Failure occurred during following action:
Creating volume group system from
System error code was: -4004

I'm wondering if this is because I'm running out of (primary?) partitions? Seems like LVM, just like Vista Ultimate, needs two partitions, one for the boot files and one for the rest of the system. I've read something about a PC drive only being able to hold four partitions, so I'm wondering if I need to get rid of that extra unencrypted partition I have in order to get OpenSUSE with LVM installed. Or am I barking up the wrong tree?

Thanks!

I don't use LVM but suspect you should have non-encrypted boot partition plus partition with encryption. Suggest to test things you make the last primary partition an extended partition, you can then create up to 15 logical partitions within it.

You will need one /boot partition having ext2/3 filesystem for LVM setup. Linux Boot Loaders (GRUB and Lilo) don't work LVMs and you have to create /boot partition for that.
