Hello dear friends,<br>
<br>
i copied the file regular-rescue-latest-x86_64.iso to the root of an
8GB USB stick, formatted with FAT32 file system.<br>
<br>
I added the following menuentry to the /boot/grub/grub.cfg on the
stick:<br>
<br>
<font size="+2" face="monospace">menuentry "Rescue LiveCD" {<br>
set linux_suffix='efi'<br>
set isofile="/regular-rescue-latest-x86_64.iso"<br>
loopback loop (hd0,1)${isofile}<br>
echo "Loading Linux vmlinuz ..."<br>
linux$linux_suffix (loop)/boot/vmlinuz \<br>
boot=boot \<br>
live \<br>
root=bootchain \<br>
bootchain=fg,altboot \<br>
automatic=method:(loop),uuid:2021-10-20-05-31-11-00 \<br>
stagename=rescue \<br>
ramdisk_size=534345 \<br>
nosplash \<br>
showopts \<br>
findiso=$isofile \<br>
iso-scan/filename=${isofile} \<br>
lowmem<br>
echo "Loading initial ramdisk ..."<br>
initrd$linux_suffix (loop)/boot/initrd.img<br>
}<br>
</font><br>
The parameters <font size="+2" face="monospace">findiso</font>= and
<font size="+2" face="monospace">iso-scan/filename=</font> may be
superfluous, the first worked for CloneZilla and the second works
for Linux Mint, but i could not yet find the corresponding parameter
name for the regular-rescue ISO image.<br>
<br>
The parameter <font size="+2" face="monospace">boot=boot</font> may
also be wrong. but the system boots up with an interruption and asks
for the exact location of the ISO image.<br>
<br>
So i guess that the parameters <font size="+2" face="monospace">root=bootchain</font>
and <font size="+2" face="monospace">bootchain=fg,altboot</font>
have to be changed that the system can find the ISO image without
asking interactively.<br>
<br>
This is what happens:<br>
<br>
1. The system boots up to the point where it says: <br>
<font size="+2" face="monospace">[ 7.754545] Starting chaind
services: [ DONE]</font><br>
<br>
2. Then the first dialog with the title "Please choose the
installation method or special action" shows up and offers the
following options:<br>
- NFS server<br>
- FTP server<br>
- HTTP server<br>
- SAMBA server<br>
- CD/DVD-ROM Drive<br>
- Local Disk Drive<br>
- Reboot the computer<br>
- Turn off the computer<br>
Here i choose the option "<b>Local Disk Drive</b>", because the
ISO file is on the USB stick, the system already started to boot
from.<br>
<br>
3. The next dialog says "Please choose the partition with the ALT
regular-rescue/x86_64 on the boot media or cancel and try again" and
gives me among others the opportunity to choose<br>
- sda1 (Part #1: 512 MiB, vfat, UUID=AAAA-BBBB)<br>
- sda2 (Part #2: 297 GiB, ext4,
UUID=01234567-AAAA-BBBB-CCCC-ba9876543210)<br>
- sdb1 (Part #1: 7 GiB, vfat: 'MAX-FELIX')<br>
Here again i choose the USB stick "<b>sdb1 (Part #1: 7 GiB,
vfat: 'MAX-FELIX')</b>", becaus e the ISO image is located there
in the root directory<br>
<br>
4. Then the last dialogbox appears and asks:<br>
"Please enter the full path to an ISO-image containing the ALT
regular-rescue/x86_64 or leave this field blank to use mounted
partition 'as is', or cancel to return step back."<br>
I input the path in the field "ISO-image"; <b>/regular-rescue-latest-x86_64.iso</b><br>
<br>
After choosing < OK >, the system boot continues with<br>
<font size="+2">[ 80.123456] INIT: Entering runlevel:
2 [ DONE ]</font><br>
and finally ends up with the root prompt, waiting for commands.<br>
<br>
Could anyone please help to correct the kernel boot parameters the
the root filesystem can be found in the ISO-image at the end of the
bootchain process that the interruption for user input is not
needed?<br>
<br>
Thank you very for your attention.<br>
Thank you very much in advance.<br>
<br>
Your truly<br>
<br>
