[Résolu] Ubuntu 20.04 lent au démarrage

Bonjour à tous,

Il y a deux ans, j'ai mis mon ubuntu sur un SSD rien que pour lui, et j'ai fait l'expérience d'un démarrage ultra rapide.
(j'étais tellement contente que l'an dernier, j'ai mis mon windows sur un autre SSD rien que pour lui aussi)

Ces derniers temps, comme mon démarrage prenait plusieurs minutes, j'ai décidé d'investiguer pourquoi. (surtout que windows, lui, boot en quelques secondes)

D'abord, j'ai tout mis à jour, je suis passée de 18.04 à 20.04. ok, super.
Mais toujours plus de 3-4 minutes au démarrage.

Je vérifie mon disque de démarrage, qu'il n'est pas plein, je vois pas de problème

/dev/sda vendor: OCZ model: AGILITY3 size: 111.79 GiB 
Partition: ID-1: / size: 97.76 GiB used: 46.06 GiB (47.1%) fs: ext4 dev: /dev/sda1 
           ID-2: swap-1 size: 11.96 GiB used: 0 KiB (0.0%) fs: swap dev: /dev/sda2

Je cherche sur ce forum, et je découvre la commande magique

systemd-analyze time

et surtout 

systemd-analyze blame

J'ai vu alors que Ubuntu passait 1 minute 30 à chercher deux disques sur la machine d'à coté qui a probablement changé d'IP (timeout, tout ça).
J'ai donc modifié mon fstab pour retirer le montage automatique de mes partages foireux, et j'ai redémarré, toute confiante de gagner mes fameuses 3 minutes !

Malheureusement, après plusieurs essais, j'ai toujours un temps de démarrage digne d'un HDD et non d'un SSD, en plus de 90 secondes :

================================= User choice ==================================

Is sda (ATA OCZ-AGILITY3) a removable disk? no

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub2 of
sda1 into the MBRs of all disks (except live-disks and removable disks without OS).
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix     

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your BIOS boot on sda (ATA OCZ-AGILITY3) disk!

Re : [Résolu] Ubuntu 20.04 lent au démarrage

Ah bah oui, en effet, c'est quoi ce swap sur /dev/sdb6 ?
Surement un reliquat d'une vielle install.
Bref, je l'ai retiré de mon  /etc/fstab

Et j'ai gagné mes 90 secondes !!!

Merci merci ++++
