[SOLVED] Installing Slackware 14.1 dual boot windows with efi

hottdogg · 01-11-2014, 11:22 PM

Dual booting with windows on my laptop, I usually 'upgrade' slackware by installing newer slackware version to / partition and leave my /home partition as it is.

Now with newer laptop I have win 7 and slack 14.0 installed. I want to upgrade to 14.1 the way I did it before like above. But slackware 'setup' menu prompt me something like this...
that my laptop is EFI enabled and I need to make space at first part of hdd for efi partition 100mb to allow the system to boot. Is that necessary?
THat will destroy my ntfs boot partition no?

Here's my parted /dev/sda print

Code:

Number  Start   End    Size    Type      File system     Flags
 1      1049kB  106MB  105MB   primary   ntfs            boot
 2      106MB   134GB  134GB   primary   ntfs
 3      134GB   268GB  134GB   primary   ext4
 4      268GB   500GB  232GB   extended
 5      268GB   495GB  226GB   logical   ext4
 6      495GB   500GB  5177MB  logical   linux-swap(v1)

So, what should I do now so I can still dual boot?
(My current system use lilo but if i have to use grub2 so be it)

As far you don't touch the ntfs partitions, you'll be fine!
Don't worrie about EFI, that wont interfere with anything.
Now a side note, why do you need a 134Gb space for the root partition? 30Gb would do just fine and you would still have enough space left.
Just do things as you have, everything should work just fine.

Dunno,I forgot why I did that. Maybe I wanted to have same space as my windows partition.

What does it say exactly and when it does happen ?
Could you reproduce it here?

Regards

You must boot the Slackware DVD in legacy mode, because you installed Windows in legacy mode.

So go to your firmware boot menu and choose the right entry. Once the ISOLINUX prompt shows on the screen, you got it right. If you see GRUB instead, you are in EFI mode, then reset the PC and try again.

Firmware boot menu? You mean BIOS menu right?...

Apparently you are right, I had to change to [legacy first] about booting efi/legacy (I forgot the exact wording) in my BIOS.
And then I booted my slackware 14.1 dvd again and yes there was no grub like it had before that and I proceeded installation as usual.
No dialog about installing EFI partition appeared. Woohoo.

jtsn, thank you very much...you're da man
