G'day,
I'm hoping to convert an Acer E-51 laptop with Windows10 to a triple booter. Keeping a reduced Windows10, trying Mint, and then a collection of 64-bit Puppies.
1. With the W10 drive wizard, I shrank Drive C from 900GB to 130GB and made 3 new ntfs partitions, for Mint, shared data and Puppies (later convert one partition to ext4).
2. I removed the several BIOS security boot hurdles and inbuilt W10 obstructions, and installed Mint from a USB to one of these new partitions. Turning the computer on, Mint now gives the expected black and white boot screen, Mint as first option followed by a few other lines including Windows. Mint runs well as does the original Windows 10.
3. With more BIOS editing and trials-and-errors, I enabled booting from a USB of BionicPup-80. I installed the Grub2config pet to this USB Pup save-file which now shows in the 'Menu' next to the Grub4Dos old app supplied with BionicPup-8.0.
4. Grub2config running from the USB shows the installed OSs (Mint, W10) plus some manual Puppy 'installs' (screenshot 1).
5. When I click to add the new boot set-up to sda2, I get a failure message (screenshot2).
In case it will help, I took shots of sda2 root (screenshot3), EFI on sda2 (screenshot4 not loading?) and sda2/EFI/boot directories (screenshot5 not loading).
How can I fix the Grub entry to achieve adding Puppies to W10 and Mint?
Is editing Mint's config file (its menu.lst equivalent somewhere on sda2?) an easy alternative?
This is all new to me - I'm used to computers >10 years old so this laptop is a 'new trick', or will be if I can be told what to do.
Thanks.
David S.
