I have installed Windows 7 with two partitions (C & D drives both have 60GB each)on my 160 GB HDD. Now I want to install Ubuntu 14.4.2 on the unallocated remaining disk space. Please tell me what should be the disk partition for installing Ubuntu on this Intel-i5 system having 4 GB RAM if I opt to install Ubuntu by selecting "something else" option. Also let me know is there any mandatory % of disk space required/specification for allocation of
swap
,/
,/user
,/home
, etc.Sometimes, it happens that after installing Ubuntu alongside Windows 7 as dual OS, the boot option menu did not show and can not log in to Windows OS. Tell me please how can I solve this issue

Whatever you want since we have hardly any restrictions. If you want you can have 1 massive partition named "/" or have 2 partitions 1 named "/" and 1 named "/home" for your personal data.
The only restrictions we have: you must have a partition named "/". All partitions that have system related files (ie. "/" and "/home" except for the user dirs in "/home") need to be formatted in a file system that is POSIX compliant. "ext4" is the current default.
Size can be calculated on how you use your system but 10Gb/15Gb can be enough if you use a "/home" for your personal data. If you want to use mysql for instance your "/" might need a bit more. I hardly reach 10Gb on "/" and use my system with some test databases using mysql.

- Re-install grub. Example: How can I repair grub? (How to get Ubuntu back after installing Windows?)
- You might also want to install "boot customizer". It is a tool to edit and view your boot settings.

Other note is partitions should not e in Windows formats such as NTFS, VAT32, etc. Use EXT4, (the default format used) or something else if you know about other Linux formats. Jul 15, 2015 at 14:05

If you have only 60 GB total space for Ubuntu, I suggest this split:
4 GB for swap
The rest for /
It does not make any sense to have separate /
and /home
when there is very little space.
This is not related to Windows at all. Just a general recommendation.
/
and/home
