Problem:
It takes too much to start Ubuntu 14.04.2 LTS 32-bit (7 minutes after the Grub screen).
Problem description
- I turn on the PC
- 1 minute after the Grub screen appears
- Once selected Ubuntu as the operative system it starts the process of loading the OS.
- 7 minutes later, the login screen of Ubuntu appears.
- Once Ubuntu starts, everything works 100%
Computer description
- Laptop ACER Aspire 5542-5770
- CPU: AMD Turion II X2 M500 – 2.2GHz, 1MB L2 Cache
- Video card: ATI Radeon HD 4200 Graphics up to 1919 MB HyperMemory
- RAM: 4 Gb
- Hard drive: 320 Gb (/dev/sdb)
- Ubuntu is not installed in the laptop hard drive, it's installed in a portable hard drive connected through USB.
External hard drive Toshiba 500 Gb (/dev/sda)
- /dev/sda1 – ext2 - /boot – 2 Gb
- /dev/sda2 – ext4 - / - 50 Gb
- /dev/sda3 – extended
- /dev/sda5 – linux-swap – 2 Gb
- /dev/sda6 – ext4 - /home – 172 Gb
- Free – 240 Gb
Records from boot are useless. All the records start 30 seconds before Ubuntu starts, meaning that they start 6 minutes and 30 seconds after the Grub screen.
Solutions tested (It didn't work)
- /etc/default/grub: I tried modifying this line: GRUB_CMDLINE_LINUX_DEFAULT=""
- I tried using all this parameters: splash – quiet – noapic – nolapic – acpi=noirq
None of this makes a change at all.
I am also sending all the reports, and it must be taken into account that I turned on the computer at 22:00.

Edit
It is not a problem of USB speed. In another computer it tooks less than one minute to start, so the problem is my Laptop.
