[CentOS] Kernell

Hi, I think during rescue mode we cannot access internet. I thought by installing kernel again will solve my problem. But after deleting I cannot retrieve back kernel and I can see rescue menu only. Please help asap. Thanks in advance. Shiva -- Shiva Prasad Nath 92981134

Re: [CentOS] Cannot boot

You have to boot from a live boot disk, chroot into your old system's filesystem, mount all partitions properly and then download and rebuild the kernel and grub config. You can try just "yum install kernel" aswell, but I'm not sure whether it'd work. Best regards, -- Sander Kuusemets On

It should be looking at /6/ instead of a specific point release. We (CentOS) do not provide updates for individual point releases. You are several years behind in security and bug-fix updates. Once a specific minor version is expired, it is moved off the main mirrors and into the vault. The
