Thanks to all that have contributed to my flaky understanding of this issue!
I've been trying to boot both laptops with TC, the VAIO via the grub I'm already using with a folder in sda2 with the necessary folders/files included there, from the cfcard too & the HP with the card in usb adapter (always the card was used with the adpater for usb). Never have seen a window with anything on it that tells me that TC is trying to do something.
So, I'm going to concentrate in trying to boot the HP with TC in the cfcard only. All editing have to be made in the VAIO, though.
The HP gave me an error message as follows:
"Try (hdo,0): EXT2: No grldr
Try (hdo,1): Invalid or null
Try (hdo,2): Invalid or null
Try (hdo,3): Invalid or null
BIOS: Drive=0x0, H=2, S=18
There's some more info but I deem it not congruent with this issue"
Have tried some different configurations of menu.lst when tried to boot the VAIO (frugally) but always the default OS booted up, but this last piece isn't important anymore.
Does anybody here is booting TC in a laptop via usb installation? If so, can you post your settings below?
Thanks in advance!
PS. I've been given a variety of configurations for grub's menu.lst but I don't know for sure what boot loader was used for Core Plus (guess was Grub4Dos). Can't I put a "pointer' in my menu.lst file for the boot loader in the sdb1 (cfcard) for making this last one boot TC? If possible it might be even easier than frugally doing so as I do the puppies I already have!
I was reviewing that menu.lst file that I use in the VAIO for frugally booting it up & discovered what I believe is an error: when trying to boot frugally I was referring to the partition of the hdd (sda2) but the UUID of the cfcard was included there anyway. I'm trying now to reboot after inserting there the sda2 corresponding UUID to see if this helps...
I'm posting this now because have to reboot. Tell you after I'm up again with the outcome of it.
Edit: I rebooted about 5 times but my PL528.005 was always the booted OS. I'm going to make a little change in menu.lst & try again.
