For FAQ readers:
The author of our very own faq provides supremely useful information, and I thank him for that very much. It's gotten me out of a jam a few times.
It is also apparent that he is aware of YUMI, but perhaps wasn't aware of the simple fix for finding the extensions. (placing the cde directory into the root of the drive, and renaming that directory to tce). In those days, perhaps there was no automatic search for tce in the root of drives.
So no disrespect - BUT he brings up a good point about using UUID's and LABELS to "anchor" to the boot drive we just made.
If you have followed the above, but STILL arrive at just the command prompt, you may have another sdx device in the system - perhaps necessary or permanently part of the device.
If that is the case, and if TinyCore still can't find the tce directory in the root of the drive, we can force it to be recognized.
YUMI by default labels the drive it creates with the label name of MULTIBOOT. Let's use that to our advantage by editing this grub.cfg file again:
/mnt/sda1/multiboot/TinyCorePure64-10.1/EFI/BOOT/grub/grub.cfg
In the tc and tcw area (I just use tcw all the time since it has the necessary delay factor), edit the word
cde
to
tce=LABEL="MULTIBOOT"
In fact, you'll see in our faq that the author has used this label name as a demonstration for using labels. Most will gravitate to using UUID's, but for now, this is the simplest solution as it is unlikely you already have a device labeled MULTIBOOT.
Note that I've tried the LABEL= both with and without quotation marks, and it still seems to work.
