Thanks for that Moulder, I don't need nvidia drivers or any locales other than en_GB and I can cope with GPT no problem.

I am watching this space!

I would agree re the --delete option,  I always use the 'n' option first before running the command for real. The 'n' option gives you the opportunity to do a 'dry run' first,  and with the 'v' option (verbose), you get to see what the command does before running it for real.

Well rayburn has now finally found time to reply.... : )

Thank you so much Miyo for going to that trouble, I really appreciate it. I did give up on that problem eventually and reinstalled a fresh version, the problem with the menu has disappeared (for now....).

My thanks again for all your help, and apologies for the long delay in replying, but I have been very busy with work.

@Miyo

I downloaded and installed your Openbox rolling iso and after a recent update i now get this message instead of a menu upon right clicking on the desktop:

Invalid output from pipe-menu "/usr/bin/obmenu-generator -i"

I have tried searching for a solution to this problem without success, so am now hoping that you or someone else can help me!

Thanks.

Next problem (and thanks to Miyo for resolving the root issue!):

root@miyolinux:/# grub-install /dev/sda4
Installing for i386-pc platform.
grub-install: warning: File system `ext2' doesn't support embedding.
grub-install: warning: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.

It is not an ext2 partition but ext4:

@HoaS
Thank you for your reply too, and yes I am using your perl-linux-desktopfiles package.

This desktop is a BIOS system without any UEFI on it and the only distros on it are Miyo ones, so I don't think that is the problem?

I have installed Miyo Wmderland but didn't install grub at that time not wishing to upset the grub that was already installed (on miyolinux). Now I can boot into the original Miyo but I can't work out how to update grub? I am used to using 'update-grub' and 'grub-install' commands on other distros, but that is not working in Miyo!

Thanks for any help.
