How to install linux on eSATA drive without writing to primary disk?
Hope this will not be a double post - my first attempt to post seem to have failed.... :?
I have a corporate Dell laptop (with Windows 7 :() and naturally I would like to also be able to run Linux on the machine. Problem is that the primary disk is protected by "pointsec" full drive encryption and all system areas (MBR etc) are scanned against a checksum causing boot to fail if tampered with.
Since I have an external eSATA drive enclosure handy I thought I could install Linux on that and use at home when I want to run Linux (selecting to boot from it in the BIOS boot drive selection menu).
I must however be 100% sure I can install without the processes writing ANYTHING to the primary disk (this would either corrupt the encrypted disk or cause a boot failure).
Do anybody know of a distribution that easily can be installed like that and in that case how would I go about the installation (to prevent writing to main drives MBR etc)?
I tried to remove the primary disk (to fool the Ubuntu installer to install to the eSATA drive only) but my stupid laptop seemed to hang on power up if no primary hard drive was installed instead of booting from the DVD so that plan did not work :(
All advice and suggestions are appreciated (note I want to make a full install where I can add programs and change settings not just run a live CD or something like that)!!!!
