    I created a Centos VM:

    Filesystem               Size  Used Avail Use% Mounted on
    /dev/mapper/centos-root  9.4G  3.4G  6.0G  37% /
    devtmpfs                 895M     0  895M   0% /dev
    tmpfs                    911M     0  911M   0% /dev/shm
    tmpfs                    911M   11M  901M   2% /run
    tmpfs                    911M     0  911M   0% /sys/fs/cgroup
    /dev/mapper/centos-home  953M  953M  652K 100% /home
    /dev/sda1                497M  163M  335M  33% /boot
    tmpfs                    183M   60K  183M   1% /run/user/1000

    I would now like to create an FTP server. I am unable to download the iso since there is not enough space in /home. Do I increase the /home or is it possible to download to the /dev/mapper/centos-home?

    Thanks, but I want to install it on my PC to try it. I have 2 partitions NTFS I don’t want to delete it.

    Thank you sir, this tutorial really helped me. First I tried to use unetbootin but failed, then I used RUFUS and it worked. I asked permission to rewrite this tutorial to my blog.

      That’s great, yes Unetbootin sometimes failed, RUFUS always works. Sorry you can’t re-publish this article on your blog.

    Install CentOS from UEFI, not Legacy, because Windows is surely installed via UEFI. In Windows cmd with admin privileges run: bcdedit

    Identify CentOS efi partition and run:

    bcdedit /set '{bootmgr}' path \EFI\refind\refind_x64.efi

    Adjust path with bcdedit output result.

    After booting to the usb i get this:

    Minimal BASH-like line editing is supported. For the first word,
    TAB lists possible command completions. Anywhere else TAB lists
    possible device or file completions.
    Grub>  _

    Im not using server grade tech.

    I built a custom pc into a 4u server with the following specs:

    -i7 8700
    -MSI Motherboard
    -Samsung 850 PRO (OS Drive)
    -Samsung 850 EVO (Storage)
    -32GB ddr4 ram

    Any idea what my issue is? I have tried installing so many times. I have turned on Legacy and turned off secure boot.
    ive tried a different USB and even a different cpu and mobo. ive installed centos 7 on a usb at least 10 times. ive tried minimal, dvd, and everything. NOTHING works. but i can load windows 10 on it no issue haha. Ideas?
