Mac OS slow boot up

Hello,

I am new here and would like to say hello

I have a new iMac (2011) upgraded to lion. I performed the safari update yesterday. It asked me to reboot so I said ok. Upon reboot I saw the apple screen then the pinwheel for about 5 mins. Then I see the unix commands in the background telling me to hard reboot. So I do that now my iMac takes 5 mins to boot. After boot everything is fine. I have reset pram, verified permissions, verified the disk and all good. I get this in verbose mode

Running fsck on the boot volume
**/dev/rdisk0s2 (no write)
**root file system

Executing fsck_hfs (version diskdev_cmds-540~34)

Hfs removed 0 orphaned/unlinked files and 6 directories.

That is where it sits for about 4-5 mins then boots


please any other ideas, otherwise apple care it is for $150.

Try booting off of the recovery partition and verifying/repairing the hard drive.

Not to sound dumb or naive but 1. how?? and 2. Will I loose any of my items on my hard drive? I am VERY new to mac Bought in June... I did go thru disk utility and verify the HDD...

Also go into System Preferences > Startup Disk and make sure your boot drive is selected by clicking once.

I only have the internal drive showing in that screen and it is selected

Downloaded onyx and now the **** thing will not boot up at all.
I guess apple care it may be.

Ok so before I tried apple care I did a network restore off my time capsule and back dated it 2 weeks and bingo. I did the safari and iTunes updates rebooted and it is the way it is supposed to be. I honestly forgot about the TC. I don't know why onyx cleaning disrupted to the point it would not boot but oh we'll all is good. Thanks for the help
