the first is typically set in your BIOS somewhere.
Second, how did you set up your persistence ? Here is how I do it.
Mount your usb device, and cd to the root of the device. Assuming it is mounted at
# this will make a 1 Gb file for storage
# increase / decrease the count as needed
dd if=/dev/zero of=./home-rw bs=1M count=1000
# Make a file system.
mke2fs 1.41.14 (22-Dec-2010)
home-rw is not a block special device.
# Answer ‘yes’ here
Proceed anyway? (y,n) y
#Remove the reserved blocks
tune2fs -m 0 -L home-rw home-rw
When you boot, you need to add the boot option
persistent to the options.
NOTE the file nema
home-rw is for a persistent /home directory only (IMO it works better). If you want a persistent / directory, change the name from home-rw to
casper-rw. Take care with a persistent /, I would not advise you install or upgrade a bunch of packages, it takes a lot of space and is not always reliable, IMO better to remaster the live CD.
