grub won't make bootable USB - trying to upgrade from old pc


chicken and egg. upgrading to new pc, but not looking to "change OSes"

i'm using older grub and it wants "a bios drive" (it refuses to see USB disk as a drive). the older bios doesn't support booting from USB (the new computer does).

I want to install an (mostly same) linux OS i'm already running - i'm not looking to upgrade or change OSes.

Should i use KNOPIX USB in the new computer, will it knop how to make a (grub) bootable on a (different) flash so i can boot the older OS from flash on the newer computer (assuming i configure the kernel location on the flash and or HD if i ever get on the new pc's hd)?

Or should I compile a newer version of grub? does (ie, grub2) write to flash even if the PC doesn't see it as a bios drive?

USB boot is a function of the BIOS. If the BIOS doesn't support it, it won't work. Why don't you tell us the make and model of the system. And, USB boot of a live system doesn't involve grub. If you can't set the option in the BIOS setup to use USB as a boot device, you can't boot off USB. But you probably can boot off of a CD/DVD.

perhaps i was less than clear. the old PC having linux installed (2.6.x) making the boot disk doesn't support USB boot, but the new-ish PC that will be booting does support it. the new pc cannot make the grub boot disk because it has only win10 on it currently

i'm trying to compile grub-2.02 but it's just finished it had bugs compiling in 32bit cpu (it won't compile if your cpu is 32bit due to ./configure hacks, as usual compiling that kind of wares). perhaps it will work i don't know.

it could be i should run a KNOPIX on the new PC not the old to make bootable grub flash to boot the OTHER os that i use. i have no idea if that's an advantage or nothing.

No perhaps about it.
So you have an old distro running unsupported boot-loader on a 32-bit BIOS machine and you insist on copying that over to a newish 64-bit EFI machine that could have anything you want on ?.
If you have old/illegal software that you need to run you might be better off installing a decent distro and simply run the old system as a virtualised guest.

your suggesting i might have illegal software?

you can fool newbies but not me: MONEY MATTERS. no i cannot "run anything i want". also i already suggested i might boot something newer to aid installing the older: but WHICH / what order will actually work is a question.

virtualization has been a topic many have had BUGS with and spent long times installing. i want neither of those headaches. also: MONEY. microsoft money. you might be their salesman - i wouldn't doubt it. Windows 10 Server is a $150 or so upgrade from Windows 10 Home. and my processor supports only 1/2 of the full hyper abilities in hw.

Your saying "run anything" but your saying I have to

#1 make purchases (microsoft, chips, etc)

#2 submit to microsoft and ubuntu policies - both which are political and involve power struggles of who has power and funding, and eves dropping: of listening in for financial or other info, of managers rooting the user's machine

#3 no thanks. i'm not impressed by a wise a*s from australia pressuring me to run things that don't do me a bit of good

if i want those problems i can do that running Windows 10 and an ubuntu bash shell, can't I ?

-------------------------

the topic isn't that i wish to run some software

the topic was making a grub or grub2 disk that can boot linux or windows 10 on a newer pc using either (old, or the new which would require some distro on a flash: which i is appropriate i have no idea). grub(2) i assume can load any kernel version capable of running on the pc, which is not your concern

it isn't a question of your concern what i do and do not need inside the / or what i run

The older OS may never boot on newer computer, how old is old? You should be able to install grub2 to usb from a live cd on old computer

your right per say. i have no preference whether i upgrade the kernel of the "old OS" to newest (running gcc-4.4.5) or whether i use a modern usb flash diskless unix to help me

but i got a grub2 disk working easily and think i don't need the above i think i just need to figure out when usb drive letters appear during boot process (chicken & egg issue i'm guessing). the benefit of having a booting flash is not having to do it all again? (perhaps not - perhaps next upgrade things will be so different i have extra work again anyhow)

because this thread went off topic i made a new one i started a new thread
