I can't seem to get into Windows 8 PreOs Mode to execute a number of AOMEI actions.
Also, holding down the shift button while clicking apply does nothing.

is there any error information during the operation? Please send more details information to here or to AOMEI support team,
Thanks for posting here

About this problem I felt sorry. I wonder to know what you want to do, what is the error message? Please try complete the operation one by one. Or you can creae Partition Assistant bootable CD to manage your disk.
