Seems like version 2A creating automated installer is not suitable solution. I've made couple of installers from different appstore files, all the same, install always fail... "About 0 seconds remaining" no restart will follow. Don't know maybe all appstore files were just corrupted...
Now i created new installer by classical copy-paste method (in guide as method 2B), it worked well, 10.10.2 installed now, no any error messages.
Thanks for the reply. I believe best recovery is compressed disk image backup, couple of minutes to copy and everything is back. Of course it does not resolve questions if you have open works etc, so you may lose some data, but i can take the risk and live without recovery partition. Also you can always try just install over the corrupted system, may succeed and maybe you'll lose nothing... you can backup your files and make later permanent recovery from early premade disk image.
Strange, with Mavericks the iasl worked well, now i got error, what i'm doing wrong or 10.10.x does not have support for iasl ?You can never open an aml directly... always must disassemble in a group.
