I was using mylivecd successfully till Nov-2010. After that I gave a long gap. (I gave long gap only for backing up my system, but I was regularly upgrading my system during this period). When I tried to remaster my system using mylivecd, image was created, but I could not boot after writing that to a disc (I could/did not find the reason for failure at this stage). There was no error reported after writing the disc.
Then I searched this forum and saw that the script uses xz compression by default and xz needs kernel 2.6.38, so I upgraded the kernel to the latest available (kernel-188.8.131.52-pclos1.bfs). I tried to remaster using xz, but no success. I tried using gzip, again no success. (At this stage I noticed the error in booting by using no boot splash option. Error is failed to mount livecd).
I had unmounted all the partitions except root during all the remasters. I have sufficient free space in my root partition. Running df gives the following,
[myusername@localhost ~]$ df
Filesystem Size Used Avail Use% Mounted on
/dev/sda9 50G 9.6G 38G 21% /
Every time I get iso file successfully, but could not boot using it.
Since I wasted about 5 discs in this process, I tried using unetbootin. From pendrive also, the image refuses to boot quoting the same error (unable to mount livecd).
After that I tried to boot using the iso in virtualbox. To my surprise, it was successful this time.
My cd/dvd drive is working properly. It is successfully writing and booting the original iso file downloaded from pclinuxos.com.
I don't know where I am making mistake. Please somebody help me.
