grub4efi - map of ISO hangs

[steve6375]

ISO is standard XP Pro SP3 ISO on NTFS volume - tested under VBOX 5. grub4efi is patched test version from today for issue #361 OK with grub4dos 2022-07-17 test version.

[yaya2007]

My test here is normal. Probably xp ISO problems. Can you reduce the volume and send it!

[yaya2007]

Confirm this xp Can ISO be started through UEFI?

[steve6375]

No - it is not UEFI ISO just plain XP - I just tried map command to list Volume ID, etc. map command should work on any ISO ??

Same if XP ISO is on NTFS or FAT32 partition. It is standard XP ISO on an NTFS partition XP ISO does have a LOT of files in i386 folder inside iso.

It would be good if the test is normal under grub4dos for BIOS.

This ISO cannot be tested under grub4dos for UEFI.

[steve6375]

Yes, works fine in grub4dos. So must be bug in grub4efi when mapping ISO. Fails on both FAT32 and NTFS so it is not a filesystem issue. There are also other problems with map command in grub4efi. Multiple map commands fail, map --unmap does not work, etc.

[yaya2007]

First of all, it needs to be clear that the ISO file is started in the UEFI environment, which is conditional, that is, there should be an img image that starts EFI (not the previous img image that starts BIOS). If not, the ISO file cannot be started regardless of whether it is placed in the fat partition or the NTFS partition.

Why you want to use map command with older xp iso

if its works fine in grub4dos so its fine

its work in any ISO

Multiple map commands fail

Multiple map commands work fine

[steve6375]

No Grub4efi map command hangs when used on xp iso. This means there is a bug in code Try using Map command on 6 different Isos, one after the other. I suggest you test before making unverified statements!

[wdlkmpx]

Maybe grub4efi should look for a diferent menu file

• menu.efi.lst
• menu_efi.lst
• menu.lst

That way the old non-uefi stuff is left out

Or maybe there's a way to hide some menu items in efi mode with a built-in variable like %g4e%

there is no bug grub4efi map command is not grub2 loopback in fact you can say it's one parameter of it it's map ISO9660 filesystem as (fd0) so never try to map legacy boot ISOs with parameter (hd+) like (hd32) (hd33) etc... or (0x+) like (0xff) (0xa0) etc...

Try using Map command on 6 different Isos, one after the other.

bad testing from you

I suggest you test before making unverified statements!

Say this to yourself If you remember me, you wouldn't tell me that Do you remember who I am? or you still the same person who developed https://rmprepusb.com/ from long time ago

I use the the %@uefi% variable it is not defined in grub4dos, 64 in grub4efi64 and 32 in grub4efi32

So you can use

configfile /my_menu%@uefi%.lst

to go to /my_menu.lst or /my_menu64.lst or /my_menu32.lst

also, if you rename the utilities in grub4efi \ext folder you can have common batch files or menu files which use those utilities

e.g. fat%@uefi% hotkey%@uefi%

and the correct one will be called (e.g. hotkey or hotkey64)

but there are no uefi32 utilities.

[steve6375]

for map command issues - see #292

[steve6375]

same issue using fd0

command appears to work but actually has not worked.

[yaya2007]

have a try map --no-hook /xpposp3.iso (0xff)

[memoarfaa]

hi @yaya2007 I still try to see how you dial with map command in UEFI. this parameter is not documented!!!!!. but I can easily catch it from source code and quickly hit breakpoint to see what its do.

@yaya2007 map --no-hook The parameter still in development progress excuse me if make some answers in some issues By the way, I am very thanks to you if you are the same person I think, but the owner of this account encouraged me to learn a lot of programming languages C, C ++, C#, SQL and work in the field of programming as a whole So far there is no boot loader based on GNU GRUB. It has this feature that starts the titles from the right to support the right to left language except grub4dos with setmenu --right - align

I see it's requested here from @a1ive and he didn't understand it
