I have this exact problem. I want to go back to the way things were and just leave the installer boot but it wont let me. If I go to "Startup Disk" from the apple menu and choose "Macintosh HD" it will tell me it can't do it because:
"Startup Disk could not gather enough information on selected disk"
it cant and that it "could not gather enough information" .... At this point I'd rather just backpedal from this installer more than anything else. I'll be able to repair the disk and worst case scenario at least just back up my files before i start again. Any ideas?
Some further info to put on the table - here's what I get after I run disk utility and this includes when the snow leopard disk is at hand:
Verifying volume “Macintosh HD”
Checking file systemPerforming live verification.
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Incorrect number of file hard links
Bad hard link creation date
(It should be 3325742596 instead of 3340504404)
Hard link record has data extents (id = 2888169)
Checking multi-linked files.
The volume Macintosh HD could not be verified completely.
Error: This disk needs to be repaired. Click Repair Disk.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
How can I even back up my files when I can't even access them because of this installer boot mode!
Someone help, please. At least to just get me out of this installer boot mode.
Okay I just tried that and it wouldn't work. At the grey apple screen it just gave me the spinning grey wheel/gear and stayed like that for several minutes until I eventually held the power key and started normally.
I also tried holding down option and it brought me to the boot selection, but it only had one option - "OSX Installer"
I have the EXACT same thing happen. I am now in limbo with no where to go. In my disc utility, repair disc is greayed out. Cannot exit the installer, and do not want to reinstall Snow Leopard, I do not want to wipe my HD clean. Someone needs to fix this. I've never had a problem like this, my computer is in limbo.
Thanks, Steve M
Likewise same problem here.
Tried also selecting the boot disk to the original, internal disk and it says it hasn't got enough information etc, same error.
Tried the restore from TimeMachine option as well, but with no luck since it does not show the internal disk as an option to restore the data?
Did I understand correct that the next steps would be:
1) Try to boot from SL installation disk and repair the disk from there
2) If that fails, erase the current partition and restore from TM, assuming it will now show the volume as an option?
Hey I just spent half the day trying to install Lion—never ending loop of rebooting, disk is damaged, etc. I tried taking out 3rd party ram. I tried a differnt drive—thinking it was my 3rd party SSD.
I zapped the p-ram as mentioned by Graham Perrin and we're finally installing.
These disk repair errors are so usual to me over the years even before Lion. I assume you are stuck having files on internal hard drive, no way to copy them as the only way to get operating system working again would be reformatting the internal drive first. There are 2 things you could do to copy the files out of the broken partition:
- use unix console commands in Terminal that you can run from OS X install dvd, to copy files to some external memory (too difficult for some users)
- use OS X install DVD to make a temporary install to some external memory like a large USB disk or a unused USB hard disk. Then you can boot it off that and use Finder to normally copy files from the broken partition to somewhere safe.
I had the same problem in the Lion install. I was able to reboot from the SL DVD (holding c during boot) and it was able to repair the hard disk (which Lion could not). I was then able to re-boot from the SL hard disk, and am now frantically backing up (which I of course should have done prior to the Lion download). I think I'll stick to SL for a while...
About 3 this morning I managed to reformat my hard drive using my snow leopard disk. Right now I am copy files from the time machine. Should take another 2 hours, I think. Can't wait to see what registration info or photographs I've lost. Can't imagine why the damaged drive info happened but shame on Apple for not giving us a way to get back to our previous condition so early in the install. Especially since this is a download and any flick of the Internet could change the installing files.
Anyway, hoping to have things clean with capability of actual upgrade to Lion.
Tried the suggestions regarding reset ram etc to no avail. Have now started with original disc, disc utility said disc cannot be repaired. Formatted disk and am now restoring from TM - 2 hours 11 mins left to go - lets see what happens then...........
Thanks for all the advice so far Gents.
