Laptop boots from shut off to grub - Zorin and Win 7 - no problem. When I reboot from either - the reboot leads to "no bootable device found" try reboot F1 or go to setup F2 or diagnostics F5. I have repeated this and it is consistent. I can shut it off and then start it - all good - but restart fails.
This is a first for me and I'm not finding anything online. I bought a refurbished Dell e6230 laptop. It passes all diagnostics. I installed an SSD (Kingston sv300 120 gig) I had used in another system. I clean installed Windows 7 on one partition (60gigs), with empty space. Then I booted from a flash drive with Zorin 16 lite and set up a ext4 partition for Zorin along with a swap (which probably won't get used as I have 8 gigs ram and this is for light duty).
Bios boot setting is set to legacy boot. Drive is recognized and is set to number one boot position.
I set the ext4 partition during Zorin installation to "/" only.
I have found nothing online like this.
P.s. I tried another distro - also Ubuntu based - Mint - same result.
So back to Zorin which was the preferred choice for this laptop.
