Super Grub(2) Disk (English) / Re: Current SGD2 CD fails Detect any OS with empty floppy drive

« Last post by adrian15 on 2013/06/02, 11:41:09 am »

I'm working in trying to minimise the floppy seeks (some improvements on SG2D 2.00 beta 5).
Can you please test it?

Removing all the floppy seeks completely won't be easy because floppy support is needed if you want to it as a floppy from unetbootin. So maybe two SG2D versions would be needed.

• The cdrom, usb one which doesn't try to seek floppy.
  
• And the floppy, unetbootin which does have floppy drive support.

I don't want to maintain two SG2D versions.

Super Grub(2) Disk (English) / Re: Super GRUB Disk on SD Card for fast Auto Boot Repair?

Theoretically using the instructions on how to make a Super Grub2 Disk USB should work.

Complain to Jordan in irc if you find instructions not being good enough.

Super Grub(2) Disk (English) / Re: Super Grub2 Fails to Detect Gentoo

It's not the case.

If you want to help post here your grub.cfg file so that we detect if you have non standard Linux kernel filenames.

Another reason for not detecting your kernels might be a strange partition type or filesystem.

Rescatux (English) / Re: Question about supergrub

« Last post by adrian15 on 2013/06/02, 11:31:29 am »

I have heard that the supergrub program, or failing that the Rescatux Linux disk, includes support for extract of .vhd files.  Is this true?

No. Rescatux is a Debian live cd, if there were Debian packages to be able to extract vhd files you could install them. But in order to do so I recommend you to use other live cds or maybe a Gnu/Linux installation.

I want to, and know how to by other means, to organise an ext3 dual boot partition on my pc.  What I don't know how to do next is to convert my Oracle VirtualBox .vhd file contents by extracting it out onto a partition.  Can Rescatux Linux, supergrub help me here?

Rescatux can help you on reinstalling Grub into MBR when the files are copied. Rescatux cannot rewrite fstab (if you needed that) for you yet. For you want to do you need probably two computers, one with .vhd running on it and a Gnu/Linux, probably better as a live cd. Just copy the files by the network from one installation to the other one and then recover Grub.

Unfortunately I haven't found any howto that explains what I'm taking about but... anyways... just find a howto that teachs you how to move or migrate a Gnu/Linux installation from one computer to another one and you're done.

If, once found, you have doubts on boot issues just ask here.

Super Grub(2) Disk (English) / Dual Boot MBR for external USB drive needed

« Last post by bungeebones on 2013/05/03, 02:22:41 am »

Hi all,

I have two ubuntu 12.04 installs on a remote powered  terrabyte external hardrive connected to the PC via USB.

The pc I am currently on also has two Edubuntu installs but that point is moot (I hope) as my goal is to have the external drive boot regardless of what PC it is connected to whether it be Windows, Mac, Linux etc (and assuming its bios can be set to boot to USB of course).

I messed up Grub from the beginning by temporarily replacing the PCs hard drive with the external one (I.e. making it the main internal one) because installing the two OSs via sata was so much faster than usb. When I returned everything to normal (old hard drive back in and the external to USB) then I couldn't boot the usb drive.

I've tried a couple command line utilities (boot-repair is one I think and the other is mbr) and got nothing but I can boot into them using Super Grub Disk2 by enabling the usb functionality (that worked like a charm by the way even if it still experimental). The site I used for instructions for trying mbr was http://www.pendrivelinux.com/install-a-new-mbr-to-your-usb-flash-device/ which were

    Open a terminal and type sudo su
    Type apt-get install mbr
    Type fdisk -l to find out which device is your flash drive
    Type install-mbr /dev/sdx (replacing x with your flash device)

I typed install-mbr /dev/sdb
So, what I want to do is rewrite the external harddrive so that when I set the bios to boot to it it will work.

Running Super Grub Disk 2 without the usb enabled shows the two partitions on the main hard drive. After enabling USb functionality it shows all four installations and the external drive is showing as sdb.

If I set the bios to boot to the USB I get a black screen and error - MBR 1FA 

I'm also trying to understand the hard drive naming when the PC boots to the external. I'm assuming the external then becomes sda but I'm not sure.

Any help with these issues would be greatly appreciated.

Super Grub(2) Disk (English) / Re: Current SGD2 CD fails Detect any OS with empty floppy drive

« Last post by xDisruptor on 2013/05/01, 22:40:43 pm »

/bump

Similar problems here. The options list becomes a bit garbled every second time I press the arrow keys. Using the option that scans all disks for possible installations results in a black screen and an unresponsive system (save CTRL ALT DEL) with no output whatsoever.

- Underlying hardware is a QDI KinetiZ with 4.0 bios with an AMD Athlon2000+ 1.6Ghz.
- IDE Disk and floppy controllers are disabled by the BIOS.
- I have PCI SATA Card FastTrak TX2300 which is the one I'm trying to see if I can boot from using G2SD because the bios fails to do so natively.

Thank you for all the effort you are putting in this project and keep up the good work.

¿Puedes reportar si ocurre lo mismo con Super Grub2 Disk 2.00 beta 1?

Gracias.

Boot Problems (English) / Re: bootmgr is missing and SGD2 seems doesn't work

« Last post by adrian15 on 2013/04/07, 11:39:13 am »

I'm not sure last Super Grub2 Disk version can bypass the Bootmgr is missing error.

  Maybe if the Detect any OS system uses the ntkernel command (or whatever the command name, I know it can load a windows kernel directly) it can be bypassed.

  You were using 1.98 version try 2.00 beta 1 version instead.

Rescatux (English) / Re: I messed up grub-trying to change fonts,

« Last post by adrian15 on 2013/04/07, 11:33:15 am »

I recommend you to try to boot into your system with Super Grub2 Disk.

Probably not with the grub.cfg detect option but with the other one that says Detect any OS system.

Once in your system fix it from inside.

Not sure this is a Rescatux issue anyways.
