I guess many might have asked this. i have a prob which i couldn't find answer for.

My laptop has **256G SSD** and **1 TB HDD**. Windows boots from SSD. I installed Ubuntu within 30GB space in the HDD, with partitons (12G for `/`, 8G for `swap`, 10G for `/home`. The **disks are GPT** based, with **UEFI based boot**.

The problem is the boot time is nearly 15 mins, from the GRUB to the Ubuntu login page. Windows does that in 10 secs. And it never turns off when i shut down from Ubuntu (last time took 20 mins, until i manually shut down).

I need to know, if those are the necessary partitions. if not, please give me details on what partitions to include, and in what ratios.

I was reading about **symlinking** to SSD for faster systems, but have no idea about which partitions to symlink.

*I need Ubuntu only for another 6 months, so no need higher encryption and i can expand space upto 40GB for Ubuntu*.
