Unable to boot system after netinst installation [SOLVED]

[ckosloff]

This is a summary of wht has been done.
Copied the latest 10.7 netinst iso to USB stick using:

Code: Select all

dd if=netinst.iso of=/dev/sdc;sync

The stick worked like a charm, exactly as a CD.
Installationi finished successfully, I started it under Secure Boot, that is what this firmware calls UEFI.
However the hard drive does not boot, with UEFi enabled or diabled.
Please note that previous to installation I not only deleted partition table but filled drive with zeros, in order not to let any previous installation contaminate this one.
I think I took all possible safeguards so cannot understand what is missing, From googlineg problem I think I have to fix GRUB but don't know how to do this.
Thank you.

I think I have to fix GRUB but don't know how to do this.

That's where I'd start. Do you even have Grub? Did you install it in the right place? I ask because I once managed to install grub to a different drive.

Installer installed it on /dev/sda.

"Does not boot" is not very descriptive. Exactly what happens when you try to boot? What is the sequence of events? What error messages, if any, are shown?

I solved by directing BIOS to use CMOS instead of efi.
