[QUOTE="Lifeisabeach, post: 1353138, member: 38864"] That is very odd. Since you have backups, you have nothing to lose. You can try deleting the partitions and re-merging them with diskutil. If it works, you've saved yourself a lot of work. If not, you were going to wipe it anyway. Just be aware of one thing: the partition you have labeled as DISK0S3 is probably NOT the actual partition identifier also. The Lion Recovery Partition is supposed to have that as the partition identifier. Actually here's a better idea. Make sure you have a current backup, then boot either from the install disc or from a bootable external backup. Run Disk Utility from there and see if you can fix those partitions that way. It you can't, then you are going to have a problem reinstalling regardless and will have no choice but to use diskutil from Terminal. [/QUOTE]
