7 ult x64 GNDJZ is compressed ctl alt del to reboot

[Hkdubjr]

I'm out of town without a recovery disk, and my lap top hd was getting full so my dumb a$& thought just press the compress drive tick box, now I cannot boot get to a command prompt etc. All I could scrounge up was a vista install disk and when I try to get to a c:\ prompt it reboots any advice?
Thank goodness for the iPhone or I would have no help at all
