Resolved PLEASE HELP ME - urgent! Booting into OSX

[robertpovall]

Hi I re-sized a bootcamp partition yesterday using camptune (I think it's called that) and now when I go to load into windows it's a black screen with
"No bootable device -- insert boot disk and press any key"

Please help!! Is there a way for me to boot back into osx because it keeps going to this screen when I turned my MacBook Air back on... I'm desperate.
Alternatively how can I solve this???

Hold the option key down on boot up and that will present you with a list of bootable partitions.

Thank you that worked!
