现在比较想卸载掉, 或者升级也还能接受.. 但是怎么保证不影响 OS X 呢?

Answer 1

Take a risk and test it yourself, and it’s successful. The approximate steps are:

• Download the ISO file of 14.04 in Ubuntu environment
• Without mounting USB: dd if=ubuntu.iso of=/dev/sdb
• Enter GParted of LiveCD and delete UEFI and HFS+ irrelevant partitions
• Enter the Disk Utility of OS X, drag and drop the partition size, Apply

Attention

• I have three remaining partitions in GParted
  The first Boot partition seems to be marked as UEFI (not entirely sure, but the mark is identifiable)
  The second and third are HFS+ partitions, and the third is marked Recovery

• I failed once when applying Apply after adjusting the partition, but succeeded the second time, but the steps are the same

If you have dual systems of ubuntu and mac, first install grub into the partition where the mac system is located, then modify the configuration file, delete ubuntu, and then format the hard drive where ubuntu is located. If you upgrade, generally the grub configuration will not change much, so it is basically no problem.
