Deepin 2014 GRUB boot delay

Dual-boot Deepin 2014 and Windows 7 on a PC with UEFI firmware

Deepin 2014 is the latest edition of Deepin, a Chinese, Linux desktop distribution that’s based on Ubuntu.

Aside from the fact that it comes with its own desktop environment called Deepin Desktop Environment, it also uses its own graphical installation program.

The installer doesn’t have support for disk encryption and LVM, the Linux Logical Volume Manager, but for plain-vanilla installations and setting up dual-boot systems, it works. This tutorial shows how to set up a dual-boot system between it and Windows 7 on a computer with UEFI firmware. It’s a relatively simple operation, but a few users have screwed up their Windows 7 installation trying to set it up. Hope this article makes the process pain free.

1. Shrink Windows 7’s C Drive: This article assumes that there’s an existing installation of Windows 7 on the target hard drive, and that you have enough free space on it to install Deepin 2014. If you need help shrinking the Windows C drive to free up disk space, see this forum post.

This screenshot shows the Windows 7 partitions before reducing the size of the C drive to free up disk space.

This one shows the partitions after the operation. Deepin 2014 will be installed on the unallocated partition.

2. Install Deepin 2014: If you haven’t done so already, download an installation image of Deepin 2014 from here. Burn it to a DVD or transfer it to a USB stick. Insert the DVD in the optical drive or the USB stick in a USB port and reboot the computer. Before it reboots into the default boot device, press the keyboard key that lets you access the computer’s boot menu. You should see entries on the screen that looks that like the one shown in this screenshot. The entry that starts with UEFI: Ut165 … is the one that’s UEFI-aware. Select it, then press the Enter key to boot into Deepin 2014 live desktop.

Once in the live desktop, you should see an icon for the installer on the desktop. Click it to start launch the installer. This is a very simple, easy to navigate installer. The first step is for user setup. The second step, shown in this screenshot, is where the fun starts. It is the installer’s Simple Mode of disk partitioning. It should show the Windows 7 partitions and the free space that was recovered from the C drive. Click on the Expert Mode icon.

3. Configure Deepin 2014 Boot Menu: Assuming installation completed successfully, reboot the computer and access the computer’s boot menu. You should see an entry for linuxdeepin2014. That’s what you have to select to boot into your new installation of Deepin 2014.

But you won’t see the GRUB menu because the boot delay time is too short. You only need to change it from 10s (the default) to 30s (“s” is for seconds).

After making that change, you should see the GRUB menu the next time you reboot the system, with entries for Deepin 2014 and Windows 7. That’s all. This guide should also work for dual-booting Deepin 2014 and Windows 8 on a computer with UEFI firmware.
