Public bug reported:

ISO testing 20.04 Studio daily image (20200326). Booting shows an error
"/boot not found". Eventually it reaches the Grub menu. Choosing "Try"
results in "can't find vmlinuz".

I believe the first time I booted this USB stick, it hung with more of
an error before reaching the Grub menu. Subsequent boots of the same
device seem to skip past what I first saw. I'm only seeing "/boot not
found" there. (And then "cant find vmlinuz" when choose "try without
installing"). I could burn the image again to see if that first boot is
indeed different. But, the repeatability of the "can't find vmlinuz" is
enough for now, I think.

The iso was zsynched (checksum automatically matched). I have run:
md5sum -c md5sum.txt | grep -v "OK$" to verify that the usb stick was
imaged without error.

Testing on: i3-3217U 1.8Ghz; 3rd gen core processor gfx; Broadcom
BCM43228 (Lenovo ThinkPad X131e 3367 laptop). The wifi card isn't
supported until after install. I have to use RJ45 to install. (But, it's
obviously not reaching that point.).
