You'd think I'd know how by now, but things change so much over the years, so I'm going to ask about Puppy installation for my wife's computer.
It's an Acer laptop similar to mine in the sig. It has UEFI and Win7 installed on sda3. She had been using it with Tahrpup32 for a few years with a CD boot, and the pupsave and Tahrpup sfs located on the sda3 NTFS partition. I had added a new ext4 partition just after that one, but never got around to installing Tahrpup properly in it. Bios had been switched to Legacy mode already. But as you can imagine with constant use in just booting, eventually the CDROM drive failed (like yesterday). and I've been thinking now I should do a proper install. Later I'll, update her OS to Fossa64.
I'd like to maintain the present set of partitions as-is, and retain Win 7. I will copy Tahrpup.sfs, initrd.gz and vmlinuz and her Tahrsave over to a Tahrpup subdirectory in the ext4 partition as a first step. No problems there. I also do know how to add stanzas to menu.lst in old grub to get the frugal going
What I'm not sure about is how to alter the present factory boot into Win. That's where I'd like advice. I need to be able to dual boot but don't don't want to wipe anything existing, or alter partitions, or even install a puppy. I just want allow booting to the ext4 partition.
There seem to be a million Puppy installers these days, and they sometimes do things automatically that I don't want to have happen with this existing installation. I've lost data in the past. So my question is which program should I use to alter the boot ONLY, not install Puppy or do anything else? Also I will need to run it from a USB drive, since the CD is now defunct.
Thanks for your help!
