[SOLVED] dual boot centos and slackware

sasha01 · 02-18-2017, 07:43 AM

hi again, at my work i use centos for work but personally i prefer slackware, so i decided to keep both on my hdd,

can you please suggest me the following:
install centos on first partition
install slackware after
doesn't really matter which partition and which first ?
boot setup as lilo or grub? and how.. which order etc..

my hdd is a sata laptop 160 gb, i think 40 gb slack and 40 gb centos is enouthg, i will install apache, postfix etc, plugged as first hdd at my work
and the rest i want to use as ntfs used with the usb interface to copy windows data for kit, etc. to use as for many laptops to install things.
please suggest!

many thanks!

LILO manually add for other system then Windows, grub picks it up for you, the order you want booted first depends on which system has control of grub.

size does matter.
what size you prefer to get the work done is entirely up to what you do with it.

yeah one boot loader will over write the other one,
The Highlander: There can be only one! rule applies there.

Code:

grub-install /dev/sdx (usally sda)
update-grub ( to pick up any other operating systems or kernel changes and such)

did you run update-grub after installing grub?

Not yet, but is more complicated to add centos in slack's lilo?

it depends on who is doing it. I have no luck in such matters so I just use grub. Slackware 14.2 also has a grub that can be installed.

My Slackware update-grub file

Code:

(userx@SlackO⚡️~)>>$ cat /usr/bin/update-grub

grub-mkconfig -o /boot/grub/grub.cfg

after ran

it works too

if you want LILO and slack with Centros then I think a new post under

how do I add Centros to LILO maybe needed so someone that knows more about that can help you.
