Fresh Installs Booting Only to Grub Page
verbose <off> Note: Wasn't sure until just now my previous post went out okay, wrote this as a second attempt. I'll post it anyway because it's more concise and contains slightly different info that may be helpful.
So here is the short and sour if it. Two HDs and one flash drive, all recently in ok condition, are no longer so. Installers verified, drives properly partitioned according to each OS. Both installs working and then as above, after 3 0r 5 boots and being swapped around a bit between 2 older but known good machines, an hp laptop and a levono laptop; along with the usual updates, downloads, and preferred program installations. I also ran the installer on its own a few times, and it also now boots only to the same grub page: "GNU GRUB version 2.12-9+deb13u2 Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions. To enable less (1)-like paging, "Set-pager=1" grub>."
I think that my repeated cycles of installation and crude and incorrect removal attempts have caused problems in these and other drives. A 32gb microSD card that recently went into "invisible mode" was last seen giving the libparted error, "end of file while reading /dev/sda" (mmcblk0). Another now common error is "The backup partition table is corrupt. The primary table appears okay, so that will be used".
So the question is, firstly, IS there a 'best practices' method for safely and completely removing 9660? And secondly, what can be done to revive the HDs, and then the installation usb stick? If anything can be done from the grub screen, given instructions, I'll try that first. Otherwise, any fixes that erase the contents are fine.
My bootable OS options are at the moment down to my puppy and an old LMDE 6 installer on usb. I've noticed that Of course I'll use the LMDE to enter commands in terminal, the stock puppy install I run has a lesser command vocabulary.
