What do you think about this video?

wrxsubaru02: Any idea why i cant add a partition? It does not allow me to click the + to add, it only lets me drop down partition box to 2 or more but then it says it will erase the existing partition... how do get the + to be available?

SpecialEllio: Format it, Should be an option when you right click on it.

stephangino: how do i reset my USB stick back to normal once i am done using it for the clean install ?

marleni: link 3 not working.......

OwGosHh: so if u don't wanna have that lion partition anymore (u wanna continue using the os x mountain lion), u just delete it? 

RJSingh88: When I try to create a partition, the "+" sign is blurred out and won't let me create it. I am currently running OS X Lion 10.7.5. Any advice on it?

Yannsonnboys Yannick: Thanks man it is very amazing what you do. Thanks a lot 

Maazin Ahmed: Hello Jonathan and everybody else here, I need some help ASAP. Got some Partition problems. I have got three partitons. Macintosh HD(OS Lion), Mountain Lion and Untitled(this was my bootcamp). I want to go back to using only Macintosh HD but with Mountain Lion installed on it. How do I proceed? Somebody please help me. How do I get rid of the partitions "Mountain Lion' and "UNTITLED" and add the space to Macintosh HD? 

RJSingh88: I tried creating a 2nd partition but it wouldn't give me an option to create it. How can I fix that? 

Ryan Wills: So, If I were to create a partition, could I transfer data between the two once ML was installed on the new partition?

Dhrumil Patel: i have DVD mountain lion,i also create partition but when i hold option keys only i see Mackintosh HD and Recovery..what can i do now PLZ ..HELP..

TuxKey: good one ;-) are you going to use rEFIt for the dualboot ??

Mile-Hi Aviation | HD Aviation Content: would this work to make a lion partition on mountain lion?

Darien Balgobin: nice vid

Ryanthemagicalwizard: So however much memory i dedicate to the mountain lion partition will be how much storage I have to save file, music etc on when i'm using mountain lion?

spyrmac: you dind't show the actual install . launch the installer choose show all disks selecet the other partition etc 

spyrmac: i haven't done it but if you do a dual boot with snow leopard ( 10.6 and 10.7 or 10.8 ) you can erase the partition but only if you you boot from the dvd 

spyrmac: yes but i think from the recovery partition only- with disk utility . you cannot erase the partition when you have booted normally . you will need to boot from the recovery partition( hold ALT/option key ) after turning on the mac before the apple logo appears . it will show you both the Macinthosh HD and the recovery HD . and any other partions such as the extra partition you want to erase . you boot from the recovery HD launch disk utility and erase the partition from there . 

Maazin Ahmed: Is it possible to UNDO the partition?

iEasha apple: what about if i already did a partition but want to give ML more gbs

Cert: Building stuff is always in my family gene. My dad is a new york auto technician and taught me everything I need to know about cars. Now I sell car parts online to suppliment my income. So it does help when there's good guidance.
