Slow boot after installing SSD drive + Grub problem + Kernel panicks

Hey

So i just got a Samsung 840 EVO, and was ready to see my system fly, so i installed Arch on it, the instalation was kinda weird, since im in the middle of some major developing for a startup i couldnt risk to lose time configuring my all system so what i did was this:

Install Arch on the SSD (/root on sdb1) while keeping my  other Arch install (/root on sda5) and sharing the /home and /swap (on sda6 and sda7) between both systems, i installed grub on sdb also because i didnt knew what to do

So now when i boot the laptop i get the grub from sda wich only has Old Arch and windows, if i press f9 at boot and boot from the ssd i go to sdb grub that has Old Arch, New Arch and Windows, since the SSD was instaled via a caddy it doesnt get recognized in the BIOS, but strangely i get 2 Universal Hard Drives (hdd and sdd) when pressing f9

So first question is, should i reeinstall grub on sda or is there a way to put the SDD as primary?

The other problem is that systemd-analyze is giving me worst times than with the hdd, and i dont see a huge improvement with the SSD as i should. Is it because i have /home /swap on the hdd? I have read https://wiki.archlinux.org/index.php/Solid_State_Drives and did as told.

systemd-analyze

Re: Slow boot after installing SSD drive + Grub problem + Kernel panicks

Trying to fix it i broke all of it

Now im having kernel panics, I reeinstaled grub on sda so i had an entry for sdb Arch and i disabled systemctl services 1 by 1 trying to improve boot time and because boot was hanging on "A start job is running for sys-subsystem-net-devices", i disables wpa-suplicant, netctl and some others, almoust everyone network related, to have just wicd

I think the problem is related to this https://bbs.archlinux.org/viewtopic.php?id=186244 plus the fact that i have 2 grub instaled in 2 diferent disks and i think i dont have lvm

What should i do? I cant think no more, i have spent 12 streight hours trying to fix this. The arch on sda boots fine, i dont have a separate boot partition nor space on sda to make it i also cant set the SSD to be primary device because the BIOS doesnt recognize it.

Please help

Re: Slow boot after installing SSD drive + Grub problem + Kernel panicks

You did not share what the kernel panic says, but I guess it has to do with your root file systems not mounted correctly. If it happens like 75% of the time, sounds like you are using /dev/sdax and it gets enumarated differently?  Use UUID's instead.

Your "slow boot" is a seperate problem, see the thread you linked too for how to fix that.

Its a fresh install but i alredy have DE and programs, i used Helmuth script to install all the stuff, just so i didnt forget to install stuff.

No idea what this means, but if it is some third party script downloaded off the internet - use them only if you understand exactly what it does, else the chances are you will run into some problems with no idea how you got there.  For simply keeping a list of packages to install, put them in a text file and pipe them into pacman (see also here.
