Inquiry:Problem with Linux Rescue


Dear All
Can you please do me favor and let me know what is my problem with the folowing scenario :
"Please be informed that my Linux server cannot be booted and halt at the following error :
Kernel panic . Try pass init=option to kernel
So I wanted to make use of the Linux rescue to recover it . To this end , I downloaded the enigma-i386-disc1.iso from the Internet and write to USB memory stick with UNetbootin utility and change the server BIOS settings to be booted from USB Flash but I got "boot failure" error. Please be informed that my server OS is RedHat Linux 7.2(Enigma) Kernel 2.4.7-10 on an i686 . Can you please let me know if I am using the correct iso image for this purpose ?
Thank you in advance

enigma-i386-disc1.iso ?

It's a multi disc distro. isn't it? I don't think you can install it with just one disk (have you tried it, with 1 cd?)

So unetbootin enigma-i386-disc1.iso wouldn't work, you'll get into many problems. get a dvd version (single file) for use with unetbootin

I think that you are going to encounter massive problems after you've installed RH7.2 on modern hardware (and your hardware is modern as it can boot from USB). That's to say, if you manage to install it at all.

I'm not sure where that bootfailure error comes from but I can easily imagine that that has to do with the fact that the RH7.2 kernel does not understand USB or only has a very limited understanding of it.

If you have the option to choose a more modern distro, please do so. If not, let us know why and we will think with you for a possible solution.

Some ideas
1)
Boot from the CD instead of USB
2)
There are instructions on the CD how to create a bootable floppy disk for system that can not boot from CD; that was the case for my RH8 system; I'm not sure if your HW has has a floppy disk.
3)
Suggested in another thread was to install an old distro in a virtual machine. You can try that, I don't have experience with it.

Yes , it has disc1 & 2 . I can try to fill both of them by UNetbootin on just one USB Flash . You are right , I cannot complete with just one disc but why it is not being started from disc1 ?
Sorry , as I told you my Linux server doesn't have CD/DVD drive so I need to try with the USB Flash . Please help me .

Thank you for your message . Please be informed that I have to install the RedHat Linux 7.2 on this server as I have an omc application that needs RedHat 7.2 to be pre-installed . As I told you , my server does support for OS installation from UBS Flash but I don't know why I am receiving "Boot Failure" error . Please help me .

Well there are issues while using Unetbootin with custom iso. It might not always make usb bootable successfully while providing it with iso file. If the distribution is listed in the drop down list it will surely be successful but not with iso files. I have had this issue when I tried to make a usb bootable with unetbootin using G4L iso. I had to make some changed to syslinux.cfg files.

And you may need to install syslinux as well.

Thanks for clarifying why you need RH7.2. Rereading your opening post indicates that you already had RH7.2 installed but failed to boot. If that is correct, sorry for misunderstanding.

As far as I can see you did not tell us in your opening post that your system does not have a CD/DVD player. Any chance of (temporarily) putting one in?

Sorry, but can not help you further at this stage.

You can download it from kernel.org and install it. But for that you will first need to extract all the files on the usb drive and then install it. If you have a windows machine with you, you will be able to do it accurately. For windows package you will need to download zip.

Thank you very much for your reply . I found the following proposal that I am not sure if it is feasible . Can you please do me favor and take a look at it ?
"
- Insert Linux CD
- Shutdown computer
- Remove internal HDD
- Start computer
- Press F12 , select Boot from CD
- Install Linux OS
When install completes :
- Shutdown computer
- Install internal HDD
- Enter Setup
- Change Boot order to resemble :
USB device
Internal HDD
CD
"
Can you please let me know if the above procedure can give me an bootable USB device?
Thank you in advance

I do not understand some options.

If you remove the internal HDD, how can you install Linux? Where will you install it?
Theres something that you are misinterpreting about.

Sorry for not providing clear explanation . The proposed procedure wants to force the Linux installation to be done just on the attached USB , so tried to remove the internal HDD . Can you please let me know if it is feasible in your opinion ?

Sorry . I didn't get the point clearly . I have downloaded the syslinux-3.81.zip but it didn't lead to an installable application under Windows. Can you please help me ?
Thank you in advance

No you do not install it. Once you have downloaded the zip, extract it in say syslinux. And it is in d:

so go to

d:\syslinux\win32

Then run syslinux.exe <your usb disk drive letter>

Thank you very much for your reply . So according to you , the steps will be as the followings :
1- Remove the files that the UNetbootin has written on the USB Flash
2- syslinux.exe G:
3- Rebiuld the files again using UNetbootin
Can you please do me favor and confirm if the above is correct ?
Thank you in advance
