Grub Bootloader & CentOS
I'm clueless about Grub and having issues with CentOS6.6 that is installed on the box. It also has Windows 8.1 installed. I want to reinstall CentOS to version 7, but want to insure I don't wipe anything, and the bootloader remains as is, but includes the new CentOS installation. How do I go about this? I've been unable to locate some good details on how this works. Thanks!

PERLIVP(1) Perl Programmers Reference Guide PERLIVP(1)
NAME
perlivp - Perl Installation Verification Procedure
SYNOPSIS
perlivp [-p] [-v] [-h]
DESCRIPTION
The perlivp program is set up at Perl source code build time to test the Perl version it was built under. It can be used after running:
make install
(or your platform's equivalent procedure) to verify that perl and its libraries have been installed correctly. A correct installation is
verified by output that looks like:
ok 1
ok 2
etc.
OPTIONS
-h help
Prints out a brief help message.
-p print preface
Gives a description of each test prior to performing it.
-v verbose
Gives more detailed information about each test, after it has been performed. Note that any failed tests ought to print out some
extra information whether or not -v is thrown.
DIAGNOSTICS
o print "# Perl binary '$perlpath' does not appear executable.
";
Likely to occur for a perl binary that was not properly installed. Correct by conducting a proper installation.
o print "# Perl version '$]' installed, expected $ivp_VERSION.
";
Likely to occur for a perl that was not properly installed. Correct by conducting a proper installation.
o print "# Perl @INC directory '$_' does not appear to exist.
";
Likely to occur for a perl library tree that was not properly installed. Correct by conducting a proper installation.
o print "# Needed module '$_' does not appear to be properly installed.
";
One of the two modules that is used by perlivp was not present in the installation. This is a serious error since it adversely affects
perlivp's ability to function. You may be able to correct this by performing a proper perl installation.
o print "# Required module '$_' does not appear to be properly installed.
";
An attempt to "eval "require $module"" failed, even though the list of extensions indicated that it should succeed. Correct by
conducting a proper installation.
o print "# Unnecessary module 'bLuRfle' appears to be installed.
";
This test not coming out ok could indicate that you have in fact installed a bLuRfle.pm module or that the "eval " require
"$module_name.pm"; "" test may give misleading results with your installation of perl. If yours is the latter case then please let
the author know.
o print "# file",+($#missing == 0) ? '' : 's'," missing from installation:
";
One or more files turned up missing according to a run of "ExtUtils::Installed -> validate()" over your installation. Correct by
conducting a proper installation.
For further information on how to conduct a proper installation consult the INSTALL file that comes with the perl source and the README
file for your platform.
