[ubuntu] Windows 8 Dual Boot with 12.10 gone wrong - No Grub or way to boot into either

I have just bought a Lenovo Twist Thinkpad with Windows 8 pre-installed and after reading about dual booting with Linux, I installed Ubuntu 12.10 64 Bit.
Secure boot and fast boot disabled in the bios as I read.
I confess that I used the Windows disk management tool to shrink the disk instead of Gparted .
Everything worked out of the box - even the initial tests with the touch screen.
Wow !

However, I am unable to boot into Windows anymore.
Error message about cannot find 'drivemap' and Invalid EFI file.
I tried using Boot-repair via livecd and also installing directly into the Ubuntu os but after taking the defaults, the machine says fault repaired but still no way to boot into windows.
I fiddled around installing another software bootloader called reFIND
This offered me another GUI on boot where I could select Windows or Ubuntu or a repair option.
Again I fiddled.
Now I am in the situation where I cannot get to any boot menu. No Grub nor reFind option.
I land at a blue page headed Recovery and text re PC needs to be repaired.

Can someone point me to the best way to go from here.
Gparted and delete Ubuntu ?
Or what?
Knowledgeable kind person needed here.
Thx,
