Operating Systems Linux Red Hat Problem with scientific Linux multiboot Post 302891408 by LMHmedchem on Wednesday 5th of March 2014 02:15:25 PM

I can use a live CD to access my files, but I'm not sure what the best method is to fix the issue. I could use a tool like rescatux to do restore grub and then update grub, but I have never used that tool before. I could do something similar in live ubuntu, but I don't have ubuntu installed anymore and I don't know if that would cause an issue. I don't know what the similar options would be from inside of suse.

I think it's odd that I can't boot the SL install from super grub2. That usually works.

NAME
grub-mkrescue -- Generate a GRUB rescue image using GNU Xorriso. SYNOPSIS
grub-mkrescue [-o | --output=FILE] [--modules=MODULES] [--install-modules=MODULES] [--themes=THEMES] [--fonts=FONTS] [--locales=LOCALES] [--compress[=no,xz,gz,lzo]] [-d | --directory=DIR] [--grub-mkimage=FILE] [--rom-directory=DIR] [--xorriso=FILE] [--grub-glue-efi=FILE] [--grub-render-label=FILE] [--label-font=FILE] [--label-color=COLOR] [--label-bgcolor=FILE] [--product-name=STRING] [--product-version=STRING] [--sparc-boot] [--arcs-boot] DESCRIPTION
grub-mkrescue can be used to generate a rescue image with the GRUB bootloader. OPTIONS
--output=FILE Write the generated file to FILE. The default is to write to standard output. --modules=MODULES Pre-load modules specified by MODULES. --install-modules=MODULES Install only MODULES and their dependencies. The default is to install all available modules. --themes=THEMES Install THEMES. The default is to install the starfield theme, if available. --fonts=FONTS Install FONTS. The default is to install the unicode font. --locales=LOCALES Install only locales listed in LOCALES. The default is to install all available locales. --compress[=no,xz,gz,lzo] Compress GRUB files using the specified compression algorithm. --directory=DIR Use images and modules in DIR. --grub-mkimage=FILE Use FILE as grub-mkimage(1). The default is /usr/bin/grub-mkimage. --rom-directory=DIR Save ROM images in DIR. --xorriso=FILE Use FILE as xorriso. --grub-glue-efi=FILE Use FILE as grub-glue-efi(3). --grub-render-label=FILE Use FILE as grub-render-label(3). --label-font=FILE Use FILE as the font file for generated labels. --label-color=COLOR Use COLOR as the color for generated labels. --label-bgcolor=COLOR Use COLOR as the background color for generated labels. --product-name=STRING Use STRING as the product name in generated labels. --product-version=STRING Use STRING as the product version in generated labels. --sparc-boot Enable booting the SPARC platform. This disables HFS+, APM, ARCS, and "boot as disk image" on the i386-pc target platform. --arcs-boot Enable ARCS booting. This is typically for big-endian MIPS machines, and disables HFS+, APM, sparc64, and "boot as disk image" on the i386-pc target platform. -- All options after a -- will be passed directly to xorriso's command line when generating the image.
