BTW, do you have any idea, how to run TLC on a public PC with USB ports, where the BIOS is locked so you can not boot from the USB (but VBOX is available)?
No I don't, others may?
Questions
Do you have rights to modify the host bootloader?
Only if so, what is the host OS pls?
What is its bootloader?
Provide an estimate of its partitions
I am initially thinking chainload to grub legacy with grub in PBR of a spare partition such as not C if its windows
I am initially thinking I can talk you thru the unpack of an iso and copy of files onto the disk
The size of the spare partition, if there is one, also will determine whether we can use grub or grub2 or some other bootloader
--but I am skilled only with grub1 and 2 so others can help with other linux boot loaders so others can help there if needed
BTW I failed uni so umm no need to reply
EDIT
a found a wiki that may suit?
