how to uninstall porteus5.0/porteux1.6？

[nayame]

at first i am a puppylinux user，so i have many puppylinux distros to boot from harddrive，but after i installed porteus5.0/porteux1.6 on my two notebook ，both of them can not boot puppylinux，the grub menu is replaced by porteus boot menu，i have no idea how to get it back，and i can not find a way to uninstall porteus5.0/porteux1.6

porteus can be uninstalled simply by deleting all of it's files.
but..
that's not going to restore your master boot record for your original grub menu..
for that, some sort of grub rescue or other trickery will be needed.. it's possible puppy might even have the tools for that..
someone with actual grub knowledge will be along shortly, i expect, with more specific advice.

the other thing worth mentioning is that porteus's syslinux could be made to boot your puppy installs by creating entries in the /boot/syslinux/porteus.cfg pointing at the initrd and vmlinuz and appending the cmdline stuff for puppy (which you should be able to find in the grub.config (or the like))

what you said is very usefull，i will give it a try ，thank you for your answer.

You will find in this forum Ikkiboot, hope it will work to restore your grub. I think github take over ikkiboot, but I dont know the name of the iso.

Welcome to Porteus nayame.

Need more information.

Are your 2 notebooks UEFI machines? Deleting files on EFI partitions can be tricky.

Which grub are you using, grub or grub2? And how did you get it installed?

How are the harddrives on the 2 notebooks formatted? Multiple partitions, multiple formats?

I'm not sure the MBR needs to be changed and ncmp's suggestion of adding entries to the Porteus menu to boot puppylinux is a good one.

Can you access the notebook's boot menu using Alt & F8 or some other key combo?

What steps did you use to install Porteus? The ones in the USB_INSTRUCTIONS.txt file?

-update-

My system's UEFI drive's EFI folder:

Code: Select all

guest@porteus:/mnt/nvme0n1p1/EFI$ du -hd1
27M	./Microsoft
1.7M	./Boot
60M	./dell
1.2M	./grub2win
89M	.
guest@porteus:/mnt/nvme0n1p1/EFI$

In the upper case ./Boot folder is a single bootx64.efi file.

In the Porteus /EFI folder is a lower case /boot folder which contains a bootx64.efi file and 10 other files.

Hey nayame

As a last resort you could ask Mike Walsh. He is a member here, on the puppy forum he is God.

Good luck

You can use grub2config-2.1.1.pet to fix your grub/grub2 but only run on puppy linux. I did use it long time a go and it worked.

I have two laptops that are grub bootstrapped, and one A has Win7 and Lick installed, and Lick boots into a lot of puppylinux distributions, This computer uses the Porteux1.6 installation script to install Porteux under Puppy,After installation, I found that I can only enter Porteux,Can't enter Grub,Naturally, I can't enter Win7 or other PuppyLinux,Another laptop B,It's also Win7+Lick,Use Lick to guide into PuppyLinux, However, after installing porteus5.0 under puppy, you can choose to enter grub on the boot screen, that is to say, you can also enter win7 and puppy. I hope to get back the grub of the computer with Porteux, so that Porteux, Win7, and coexist, and I can freely choose the system I want to enter when I boot up.

I have been following the forum for a long time, and I feel that the forum is relatively deserted, and I didn't have any expectations when I asked a question for the first time, but I was very surprised to see so many replies, and I was very excited, thank you for your enthusiastic answers

I don't speak English well, so I used Google Translate, and I hope you can understand it

mbr boot machine ，using grub，install it in puppylinux by using the install script porteux/s images supplied，partition type :ntfs，for porteus i can access boot menu，but for porteux i can not

[beny]

h,i if you have used the install script,you have installed the syslinux into the mbr so you have grub damaged,you can try to chainloading the other system to syslinux if they are located into the same ssd,if i have undestand well or try a grub recovey,Ed_P is a master for... this task

Ok nayame, lets deal with one machine at a time.

The machine/computer has puppylinux on it, you downloaded the porteux/s iso files, some how extracted the iso files someplace and ran the porteux-installer which loaded the boot files & folders to the computer's harddrive. You then ran the porteus-installer which loaded the porteus boot files & folders to the same harddrive overlaying the same named boot files and folders previously installed. Yes?

The output of a "ls -hon" command run on the harddrive would be helpful. And a "ls -hon /boot/syslinux/*.cfg" one would be useful also.

I suspect if you look at the /boot/syslinux/ folder you should see a porteus.cfg file and a porteux.cfg file. Copy lines 30-41 of the porteux.cfg file to after line 68 in the porteus.cfg file and edit the LABEL and MENU lines to be unique. Basically ending up with something like this:

Code: Select all

LABEL GRAPHICAL
MENU LABEL Graphics mode
KERNEL /boot/syslinux/vmlinuz
INITRD /boot/syslinux/initrd.xz
APPEND changes=/porteus
TEXT HELP
    Run Porteus the best way we can.
    Try to autoconfigure graphics
    card and use the maximum allowed
    resolution. If booting from a
    non-posix (FAT/NTFS) drive,
    see the Saving Changes Help
    below for how to save changes.
ENDTEXT

LABEL fresh
MENU LABEL Always Fresh
KERNEL /boot/syslinux/vmlinuz
INITRD /boot/syslinux/initrd.xz
APPEND nomagic base_only norootcopy
TEXT HELP
    Normally Porteus saves all changes
    to the /porteus/changes/ directory
    on the boot media (if writable)
    and restores them next boot.
    Use this option to start a fresh
    system, changes are not read from
    or written to any device
ENDTEXT

LABEL graphicalx
MENU LABEL Porteux Graphics Mode
KERNEL /boot/syslinux/vmlinuz
INITRD /boot/syslinux/initrd.zst
APPEND changes=EXIT:/porteux

LABEL freshx
MENU LABEL Porteux Always Fresh
KERNEL /boot/syslinux/vmlinuz
INITRD /boot/syslinux/initrd.zst
APPEND nomagic base_only norootcopy

No guarantee this will work but it may.

If you post the grub menu for your puppylinux system we can see if it can be added also.

On a puppylinux system see if it's grub supports the loopback command.

Multi-booting is possible, just not by installing one on top of another.

I just saw this posting nayame.

I have two laptops that are grub bootstrapped, and one A has Win7 and Lick installed, and Lick boots into a lot of puppylinux distributions, This computer uses the Porteux1.6 installation script to install Porteux under Puppy,After installation, I found that I can only enter Porteux,Can't enter Grub,Naturally, I can't enter Win7 or other PuppyLinux,Another laptop B,It's also Win7+Lick,Use Lick to guide into PuppyLinux, However, after installing porteus5.0 under puppy, you can choose to enter grub on the boot screen, that is to say, you can also enter win7 and puppy. I hope to get back the grub of the computer with Porteux, so that Porteux, Win7, and coexist, and I can freely choose the system I want to enter when I boot up.

I've never heard of Lick and will investigate later but your setup sounds much more normal. So basically Porteux screwed up your system's boot process. Lets ask porteux if porteux backups up the mbr code when doing an install. If not hopefully you have a backup of the system handy.

Did you install the porteux/s systems into separate partitions?

An interesting app Lick. Do you ever converse with it's developer?

Currently only Puppy Linux-based distributions are supported.

When Lick installed puppylinux did you have to run a puppylinux-install app too?

Seeing your Lick boot menu would definitely be helpful.

When booting your systems press the BIOS key, the BIOS key is usually F2, F10, F12, F1, or DEL, but it depends on the computer's manufacturer, and post a screen shot of the window, if you can. I post screen shots to https://postimages.org/ and post the image's Forum link here.

Then see if this helps.

i can boot from grub now， to solve the problem ，i deleted all the porteux folders and installed porteus 5.01 in porteux1.6 . so that the mbr record changed ，very lucky，the grub menu comes back again，right now i can boot into porteus or win7 or puppylinux or any else

[Ed_P]

i can boot from grub now, .... right now i can boot into porteus or win7 or puppylinux

Thank you for the update nayame.

i boot into porteus，porteux has been deleted，its boot record has been covered by porteus，porteus is light weight ，runs fast . compared to porteux1.6，some apps are out date，but i don't care， it already meets my needs
