I install Windows on My Mac with Bootcamp in January this year. Last week i played FSX in Windows and i think i should extend the Windows about 50GB. Yesterday, I try to extend my Windows partition. Winclone said to do chkdsk/b, i do it, but it stuck on 30% so, i push the power button until my MacBook Pro turn off. Today, i try to switch to Windows, but when i hear the start up chime and i press option (alt) there are no option to my Windows, just to the Macintosh HD. Any way to solve this ?
