Hello,

There seems to be a recent regression:

Conversely, it works with a commit from two weeks ago:

A relevant difference seems to be GPT vs. MBR (the latter works, the
former breaks):

--8<---------------cut here---------------start------------->8---
$ cat $(guix build /gnu/store/hq7lw7qm3fbl4fhlmqxxp9sw1v8h3h3m-genimage.cfg.drv) |head -3
image image {
	hdimage {
		partition-table-type = "mbr"
$ cat $(guix build /gnu/store/dnqxyq1x7fd5131rby4z46rx8wkzw1k6-genimage.cfg.drv) |head -3
image image {
	hdimage {
		partition-table-type = "gpt"
--8<---------------cut here---------------end--------------->8---

The culprit might be 209204e23b39af09e0ea92540b6fa00a60e6a0ae, from
<https://issues.guix.gnu.org/62223>.

Josselin, Sergey, WDYT?

Hi,

Pushed d57cab764122af69d52d8cc9c843456044e5d7bc that adds mbr-image-type
and sets it as default.

LMKWYT, closing tentatively.

Best,
