I have installed Ubuntu 13.04 alongside windows 8 (efi mode) and now I want to go to a read-write access of the efi boot partition.

For secure boot to work, I installed the Linux Foundation's PreLoader. Then I enabled root account login to access the efi boot partition. I have copied the boot loader, but now the efi boot partition mounts as read-only.

When I try to change the folder permissions, it says:

Error setting permissions:Read-only filesystem

I have already tried the following command in root:

mount -o remount,rw /folder1/folder2/targetFolder

It is still read-only.

How to fix this?

Your problem was most likely caused by a new Windows 8 feature called "fast startup." This feature turns a Windows shutdown operation into a suspend-to-disk function, which in turn means that the filesystems are not properly unmounted, which means that they cannot be safely mounted in any other OS. Thus, on systems that dual-boot with Windows 8, it's IMPERATIVE that fast startup be disabled, as described here:

i knew about the windows fast boot issue with linux and already figured the way around(created a shortcut to command line shutdown that shutdows the windows in old way) and can ACCESS THE DRIVES in UBUNTU.. but i ran fsck in ubuntu and there was some cluster mismatch issue and another error found during ubuntu recovery mode a superblock could not be read. – user195216 Sep 24 '13 at 9:35
and i used the chkdsk in cmd prompt that repaired the efi boot partiion – user195216 Sep 24 '13 at 9:37

i figured it out my self ... i used chkdsk command in windows 8 and it repaired the partition.

thanks if anybody took pain to solve this .. i would have deleted this question the same day i posted it here but i don't know how to. sorry
