BIOS configuration
I have a problem with a brand new Dell laptop. BioLinux was installed on it without making the necessary changes on BIOS. The installation was completed successfully but the BIOS system cant find the OS after rebooting the machine.
I have tried to modify the BIOS setting with no luck this far. I was hoping someone here could guide me through the process
Thanks in advance

What, precisely, have you tried?

We'll need more information on your laptop than "brand new". Model would help.

This is the laptop I am referring to:

Dell Inspiron 15.6" Touch-Screen Laptop - Intel Core i3 - 6GB Memory - 1TB Hard Drive Black I3558-9136BLK - Best Buy

I tried to modify the booting order so it can recognize the OS. However, I cannot see Biolinux listed despite of completing the installation successfully.

This can have a lot of reasons and we have to start somewhere: You probably can boot from some CD/DVD/USB-Stick. Do that, open a command window and type parted /dev/sda, then press "p" (for "print") to list the partition table. The picture you see shoud be similar to this one:

Code:
Model: ATA ST500LT012-1DG14 (scsi)
Disk /dev/sda: 500GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos
Disk Flags: 

Number  Start   End     Size    Type     File system  Flags
 1      1049kB  3146kB  2097kB  primary
 2      3146kB  2151MB  2147MB  primary  ext3         boot
 3      2151MB  500GB   498GB   primary               lvm

Notice there is a 2G boot-partititon formatted as ext3. Only the rest is LVM-controlled. Linux can't boot from LVM-partitions (yet). If your layout looks very different then post it here.

I hipe this helps.

Hi.

Here is output from fdisk within a Bio-Linux system:
Code:
$ fdisk -l

Disk /dev/sda: 104.9 GB, 104857600000 bytes
255 heads, 63 sectors/track, 12748 cylinders, total 204800000 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000830ae

/dev/sda5       200607744   204797951     2095104   82  Linux swap / Solaris

On a Virtual Machine run within virtualbox:
Code:
OS, ker|rel, machine: Linux, 3.13.0-63-generic, x86_64
Distribution        : Bio-Linux (8; Ubuntu 14.04.2)

However, I have not used Bio-Linux sufficiently to be able to provide help much beyond this. Regrettably, I also seem to have misplaced my install notes.

I suggest you be more precise about ... cant find the OS after rebooting the machine by providing the exact message(s) you see when trying to boot.

Good luck ... cheers, drl

Solved the problem disabling the boot security and enabling legacy. Finally, I rearranged the boot sequence to 1) USB 2) HDD and proceeded to reinstall Biolinux. Worked like a charm!
