# <span style="color:red;">'''ATTENTION:'''</span> Mehrdad mentioned that possibly in the next semester (or eventually), the belmont server URLs will be removed. The alternative (and eventual replacement) that affects OPS235/OPS335/OPS435 is: mirror.senecacollege.ca/centos/7/os/x86_64/<br>Therefore, this corrections should be made for OPS235 and OPS335 labs for the Winter 2018 startup prior to classes.<br><br>

# <span style="color:red;">'''ATTENTION (Mark Fernandes / OPS235):'''</span> Verify your CentOS release version using '''rpm -qa centos-release'''. If it is '''1708''' <u>and,</u> you are using a '''removable hard drive''' with boot issues then do the following: copy '''grubx64.efi''' from [http://mirror.centos.org/centos/7/os/x86_64/EFI/BOOT/ CentOS EFT/BOOT site here] into your /EFI/BOOT directory of your hard drive. To get to that directory of your hard drive you would need to boot from a live CentOS USB or CD/DVD and mount the /boot partition of your HDD. Try to do this yourself, otherwise ask for help from the lab tutor or instructor.<br><br>
