Originally installed on the server is Windows Server 2003, open a number of virtual machines installed Linux to use, but found whether it is VMware or VirtualBox, there is always a memory leak, about 2 weeks or so 16G of memory is all gone, the task manager sees memory usage is full, Then not for a long time the virtual machine is not connected, Windows itself also error bomb virtual memory is not enough, but it does not crash ... Toss to unbearable, finally intend to change the system to try, the host into Ubuntu server bar.

However, according to the instructions step by step from the official website to download ISO engraved USB, installation is unexpectedly various problems:

1, using the official website recommended Universal-usb-installer do USB, on that server directly loading not up, screen a black screen, USB is flashing, is not moving ... Even if there is no way to start, had to give up.

2, with UltraISO do USB, finally can guide, select a few language and keyboard options, and hang up, always hint what:

There is a problem reading data from the CD-ROM. Please make sure it's in the drive. If retrying does not work, you should check the integrity of your CD-ROM.

Failed to copy the file from CD-ROM. Retry?
