[Bug 825172] New: Booting live USB for 13.1M2 fails on a UEFI box (Copy-on-write problem?)
https://bugzilla.novell.com/show_bug.cgi?id=825172 https://bugzilla.novell.com/show_bug.cgi?id=825172#c0 Summary: Booting live USB for 13.1M2 fails on a UEFI box (Copy-on-write problem?) Classification: openSUSE Product: openSUSE Factory Version: 13.1 Milestone 1 Platform: x86-64 OS/Version: SUSE Other Status: NEW Severity: Major Priority: P5 - None Component: Live Medium AssignedTo: coolo@suse.com ReportedBy: nrickert@ameritech.net QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:21.0) Gecko/20100101 Firefox/21.0 I prepared a USB with the live Gnome image for 13.1M2, using ImageWriter (from opensuse 12.3). I booted as a UEFI boot. The GUI never came up. On a retry, the USB was unbootable. It appears that a CoW partition was created, and creating it destroyed the boot structure on the USB. Full details are given in a forum post: https://forums.opensuse.org/english/get-technical-help-here/pre-release-beta... See comments 21 and 22. Note that "fdisk" output is given there. The CoW partition seems to have been placed where it overwrites the boot structure, instead of it being placed in the unused 2G of space at the end of the USB. I retested using the live KDE, this time written to the USB with "dd_rescue". The results were similar. It did not boot to a GUI, and the USB was unbootable afterwards.

--- Comment #5 from Neil Rickert
but facing similar issue it made my usb unbootable
This problem was discovered too late for M2. You can wait for M3 and test whether the fix works. I'll be doing that. If you are looking for a workaround, then check Dale's post at the forum: https://forums.opensuse.org/english/get-technical-help-here/pre-release-beta... I have tested that, and it works. I made a live Gnome USB. I then used "fdisk" to create two additional partitions (partition 3 and partition 4). To do that you must be careful to tell fdisk to start the new partition after the current one. Don't accept the default of it being before partition 1. I made partition 3 minimal (2047 sectors), and partition 4 the rest of the USB. I formatted partition 4 as "ext4". The idea of the additional partitions is to fill the partition table, so that a desctructive partition cannot be created. I have booted this USB twice on a UEFI box and twice on a non-UEFI box, just to test that it does not self-destruct. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
